From 206,854 reviews, clients rate our Linux Developers 4.9 out of 5 stars.My WHM-powered Linux server has become sluggish and I can’t pinpoint why. I need an admin who lives and breathes cPanel to step in, diagnose the performance issues, and bring the machine back to full speed. The task is entirely troubleshooting-focused: you’ll investigate load spikes, slow page responses, and any other bottlenecks hiding in the stack. Deliverables • A clear diagnostic report outlining root causes • Tuned configurations or commands applied (Apache/Nginx, MySQL/MariaDB, PHP-FPM, kernel limits, etc.) • A brief post-fix summary so I can reproduce or adjust the settings in future SSH and WHM root access can be provided as soon as we agree on a start time. Please be comfortable working live on production and documenting every change you make...
Project: EdgeCache – Video CDN Cache Simulator I already have the project implemented locally. It is a simulation/demo of how a real-world CDN works for video delivery. The project currently runs locally and has NOT been deployed. I want deployment to be part of the work. Core concept: User → Edge Cache → Origin Server When a user requests a video segment: * If the segment exists in the edge cache → Cache HIT → serve from cache * If it does not exist → Cache MISS → retrieve from origin → store in edge cache → serve to user * The system tracks cache hits, misses and hit ratio. * LRU-style eviction is used to prevent the cache from growing indefinitely. Current technology: * Frontend: React + Vite * Backend: Node.js + Express * Video proc...
I want to turn our manual, click-heavy release routine on AWS into a fully automated, repeatable workflow. The goal is simple: with a single commit or tag, the latest build should travel from repository to test, staging and production without human intervention—rolling back cleanly if anything fails. You’ll look at our current AWS setup (EC2, RDS and a handful of managed services) and replace ad-hoc scripts with infrastructure-as-code and a reliable deployment pipeline. I’m leaning toward tools you already know well—Terraform or CloudFormation for provisioning, and something like GitHub Actions, CodePipeline or Jenkins for the CI/CD stages—but I’m open to suggestions if there’s a better fit. Key deliverables • Infrastructure definitions st...

I need a robust automation that reliably streams around 1,000 skippable YouTube ads every day. The flow is straightforward: load a video, let the ad run long enough to count as viewed, then move on to the next. A percentage of sessions should also register a basic interaction—an occasional click or skip—to mimic normal user behaviour without getting the channel flagged. Key expectations • Handles only skippable ads on YouTube; no Facebook or other platforms involved. • Stays within YouTube’s terms as much as possible—rotating residential proxies, realistic watch-time patterns, randomised intervals, and varied user-agents are essential. • Simple dashboard or log file showing daily totals, watch duration per ad, and how many interactions occurred...
I am building a small-scale NOC around Zabbix and need a veteran who has spent a decade or more in the trenches with the platform. The goal is to package proactive monitoring as a managed service for my customers who already buy data-security solutions—UTM firewalls, endpoint protection suites, SIEM feeds and the like. What I need from you • Initial setup: architect and deploy the Zabbix server, proxy layout and database back end, tune for high availability and multi-tenant use, and document every step. • Integration with security solutions: create or tailor templates, SNMP polls, API calls and alert rules that pull health, threat and license data from leading UTM appliances, EDR/AV agents and cloud security portals, then roll them into clear dashboards and SLA reports...

I have a short on-site engagement in Sydney CBD that needs an experienced hands-on technician. The job is straightforward—about one to two hours—but I need someone who can arrive on time, work independently, and leave the workstations fully operational before walking out the door. Scope of work • Set up and configure the new workstations • Connect and configure all peripherals we’ve supplied: printers and scanners, monitors with docking stations, plus keyboards and mice • Run basic network-connectivity tests so I can see green lights for internet and domain resources • Carry out a quick hardware sanity check (cables secure, no visible faults) and confirm each station boots cleanly to the log-in screen Success for me is simple: by the end of you...

MediaTek MT8168 Custom Android ROM Installation & Technical Support I’m looking for an experienced Android/MediaTek developer who can provide step-by-step technical guidance for installing or porting a fully functional custom Android ROM to a MediaTek MT8168-based tablet. The tablet currently has a restricted Android installation, and my goal is to replace it with a clean, stable, fully functional Android version that is properly configured for the device hardware. I am currently working with the tablet in its original, unrooted Android state. I do not have root access at this time, so I will need guidance on the appropriate process for gaining the necessary access and preparing the device for the ROM installation. If I need a rooted state or a Linux environment, that can be ...
I need an external, black-box penetration test carried out against three separate /24 IPv4 ranges that power our public-facing web applications, email servers, and SIP services. The exercise must satisfy our compliance requirements, so the methodology, evidence gathering, and final reporting all have to stand up to an audit review. Here’s what I expect: • Reconnaissance, vulnerability discovery, and controlled exploitation performed strictly from an external perspective—no inside credentials will be provided. • Clear scoping and scheduling so the assessment covers every live host across the three networks without disrupting production traffic. • A written report that prioritises findings by risk, maps them to relevant compliance controls, and includes reprod...
I’m setting up a small, in-house email system and want SmarterMail installed and configured on my Windows Server for internal communication only. The environment will support no more than ten users.
I’m pushing a software project toward the finish line, but recurring glitches in my development tools are slowing me down. I need ongoing technical support focused exclusively on software troubleshooting—everything from IDE freezes and mis-configured compilers to stubborn build scripts or version-control mishaps. You’ll step in whenever a tool breaks, share your screen if needed, trace the root cause quickly, apply the fix, and leave me with a short note that explains what happened so I can avoid repeat issues. Most of my work runs through VS Code, Git, Node.js, and Docker on a Windows/macOS mix, though I occasionally spin up Linux VMs. Experience reading logs, adjusting environment variables, and juggling plugin dependencies is essential. Availability during my UTC+2 w...
I need a developer who can build a clean, reliable cPanel/WHM plugin that lets server owners route all outgoing mail through the TurboSMTP API. My servers run on Linux and I’d like to host the finished package so customers can download the installer, drop it into their own cPanel/WHM environment, enter their TurboSMTP credentials and start sending immediately. Core scope • Outgoing mail only: the first release just has to relay messages through TurboSMTP. I may revisit inbound handling later, so keep the code modular enough to add that without a rewrite. • Admin-only authentication inside WHM: the interface must respect existing WHM privilege levels—only root or reseller-level admins should be able to view or change the API key. • Seamless installation: an S...

I have a fresh server waiting for you to connect and install an open-source hypervisor—VirtualBox is my chosen platform. Once VirtualBox is in place, I need twenty fully functional desktop machines, 10 running Arch Linux and the other 10 Linux Mint. Each desktop must sit in its own isolated VM. Key requirements • Shared-folder integration between host and guest so I can move files back and forth effortlessly. • Reliable USB pass-through so attached devices appear inside the VM just as if they were local. • RDP and VNC configured on both guests for smooth, encrypted remote access. Please tune the settings for good performance over typical broadband connections. Beyond the basics, make sure the guest additions (or equivalent) are installed, networking is bridged f...
Note: We will need a detailed interview of the person explaining how will they do it, what approach will they follow and what will be turn around time of the project I need a cloud-hosted program, built entirely on AWS, that can inflate YouTube views, inject likes, and post pre-written comments several times a day without tripping Google’s abuse filters. We will start with YouTube only; once that is running smoothly I may extend the same framework to Instagram and website traffic, so keep the architecture modular. Core requirements • AWS-native: the whole workflow should deploy through CloudFormation or Terraform and run headlessly on EC2/Lambda containers, with CloudWatch keeping logs. • Actions: generate realistic view sessions, apply likes, and drop comments I suppl...
I’m bringing a new hardware brand to market and need a complete mobile operating system built from the ground up, ready for both smartphones and tablets at launch. Everything must feel effortless for everyday consumers: smooth onboarding, clear navigation, and responsive gestures. Security is just as critical. I want encryption, robust permission management, and an architecture that protects user data by default. At the same time, the interface should welcome personal style—theme packs, flexible layouts, and other custom options that never compromise stability or safety. Key objectives • Deliver bootable images for reference phone and tablet hardware, plus a reproducible build environment (AOSP, Linux kernel, or comparable stack is fine if it accelerates delivery). ...
I already route checkout traffic for the Geidia payment gateway through an iframe-based IP proxy so the request appears to originate from my VPS’s static address. That lets the initial payment page load, but once the JavaScript-based redirects kick in for 3-DS and the final callback, the flow escapes the tunnel and the gateway never notifies my Laravel callback URL. I need a clean, fully isolated solution that: • keeps every redirect—including the 3-DS challenge—inside the proxy path • forces the gateway to see only the server’s fixed public IP, never the shopper’s browser IP • returns the gateway’s success or failure response to my Laravel controller without breaking session or CSRF tokens You’ll be free to choose the mo...

My WooCommerce store on a shared SiteGround plan keeps hitting their resource ceiling. SiteGround automatically suspends the site several times a day and their logs show waves of unfinished SQL queries piling up until new requests tip us over the limit. As a result I’m facing frequent downtime, very high CPU usage and painfully slow page loads that are costing sales. I need someone who knows WordPress, WooCommerce and SiteGround’s architecture inside-out to: • trace and fix the slow queries or loops that are stacking up • review theme, plugin and custom-code interactions that might be spawning excess calls • configure or fine-tune caching (SiteGround Optimizer, object cache, browser cache) so requests are served faster instead of re-querying the database ...

I need a clean, well-structured Python OPC-UA client that can talk directly to an SLM 280 metal 3D printer and give me full, real-time control over its atmosphere management: Oâ‚‚ concentration, chamber pressure, and gas flow. The end goal is to adjust those three parameters remotely and watch them update live, as if I were standing in front of the machine. Scope – Establish a reliable OPC-UA connection to the printer’s server nodes. – Expose read/write methods so I can both query and set Oâ‚‚, pressure, and flow values without latency that would compromise print quality. – Wrap the interaction in a clear API layer (class or module) so future scripts can call it with one or two lines. – Handle connection drops gracefully and log every transaction for trac...
I have two SaaS sites running on AWS (EC2 + RDS + S3) that I now want moved to BinaryLane () . Both stacks are fairly standard—no exotic networking or custom AMIs—so this should mainly be a clean lift-and-shift and a bit of re-wiring. Scope of work • Spin up equivalent BinaryLane instances, copy the codebases, databases, SSL certificates and cron jobs, and confirm the apps are fully functional on their new hosts. • Point the DNS once we’ve run smoke tests and I give the green light. • Leave all image and document storage on AWS S3; update the apps so they continue to read/write to the same buckets without any broken links. • Recommend and integrate a cost-effective transactional email solution (Amazon SES, SendGrid, Mailgun—whichever you feel gi...

I need a specialist who can take the project from a clean slate to a fully functional, production-ready system. Here’s what I’m expecting: • Complete installation of the latest stable Asterisk on each node (one local, one cloud) with SIP trunks registered and ready. • Seamless call routing between sites, extension dialing, voicemail, IVR, and basic queue logic operating flawlessly across the hybrid topology. • Secure configuration—TLS/SRTP, strong authentication, sensible firewall rules, fail-over settings between the two servers. • Real-time monitoring and alerting set up (Nagios, Zabbix, Grafana, or a tool you’re comfortable ...
I’m running everything on a VPS and want the entire hosting stack built, hardened, and ready to sell. Here’s what I need done: • Install the stable release of cPanel/WHM together with CloudLinux 8 and LiteSpeed Web Server. • Apply best-practice security and performance tweaks for this combination. • Create standard shared-hosting packages inside WHM (disk, bandwidth, email, etc.). • Link those packages to WHMCS, set the pricing I’ll provide, and verify automated account creation, suspension, and termination all work. • Enable common addons—Softaculous, immunify360 (if you recommend), CageFS, PHP Selector—so customers can switch PHP versions safely. • Deliver a brief hand-off document with root credentials removed, outli...
I need a single Android application that brings three abilities together: • show the live HD feed from my existing IP cameras, • let me start / stop recording that feed and push the resulting files straight to my server, and • allow me to toggle an IP-based IoT switch from inside the same interface. A simple email-password login gate is required before anyone can use any feature. Once authenticated the user lands on a dashboard where the camera stream appears immediately; from there a record button begins saving footage and silently transfers it to my server (I will give you the endpoint and credentials). A separate tab or overlay houses the IoT switch with instant on/off feedback. I am open to whichever libraries you prefer—ExoPlayer, VLC, ONVIF, RTSP, MQTT, HT...

I run a large WordPress installation—about 80,000 pages—and, while I’m comfortable with server administration at an advanced level, the stack is hitting its limits. Under heavy traffic and aggressive crawler activity we see: • 500 errors under load • Indirect/server errors affecting crawlers • Slow performance under high traffic I need a LiteSpeed specialist to dive in and eliminate these issues. Scope of work 1. Audit and benchmark my current setup on CyberPanel, focusing on LiteSpeed Web Server, Redis, and MariaDB. 2. Trace the root causes of the error patterns above, then apply configuration fixes and performance tweaks. 3. Tune LSCache, Redis object caching, and database parameters so the site remains responsive during spikes. 4. Stress...
I am rolling out a new IP-based CCTV network that must protect both indoor and outdoor areas of our facility. The job begins with a full site survey—virtual walk-throughs and existing floor plans are available—to map optimal camera positions, cabling routes, and NVR locations. Because the entire backbone will run on Ethernet, you will need to size and specify PoE switches, storage capacity, and any wireless bridges needed for hard-to-reach exterior zones. Once the bill of materials is approved, I expect you to handle or oversee physical installation, perform all network configuration (subnetting, VLANs, port-forwarding for secure remote viewing), and fine-tune the VMS so live and archived footage streams smoothly from every camera. Acceptance criteria • Complete cove...
Install and setup self hosted Joplin Server with Nginx and Let's Encrypt SSL Certificate on Ubuntu or AlmaLinux VPS And Document the Full Setup Process including the commands to build out the server and configuration files.
I am moving our production DNS from a Windows-based server to a fresh Debian instance running Bind9. The new host needs to be fully authoritative for all current zones, so I will rely on you to extract every record from the Windows server, import them into Bind-compatible zone files, and validate that the answers match bit-for-bit before cut-over. Once the zones are in place, I also want DNSSEC enabled with a properly generated Key Signing Key (KSK) and Zone Signing Key (ZSK) for each zone. Please configure automatic key rollover and publish the DS records I will provide to my registrar. The goal is a seamless switchover with zero client disruption and clean validation on tools like dig +dnssec, dnsviz, and Verisign’s DNSSEC debugger. Deliverables • Debian 12 server with Bind9...
I run several sites on a Hostinger VPS and need someone who can step in each month to keep the server running smoothly whenever something breaks. The main help I’m after is hands-on troubleshooting and issue resolution—software crashes or odd errors are what crop up most often. You’ll have root access through Hostinger’s hPanel and SSH, so you should already be comfortable reading logs, restarting failing services, rolling back misbehaving updates, and applying quick patches without disrupting live traffic. When an incident occurs I’ll ping you on Slack or email; a prompt first reply and an estimated fix time are essential. Once a problem is solved, I expect a brief rundown of the cause and the steps you took so I can track recurring patterns. Typical stack...
I have a fresh AlmaLinux 10 VPS ready and need it converted into a fully-functioning hosting node. Your job is to install WHM/cPanel, hook it into WHMCS, and make sure the environment is production-ready on first login. The core installation must include the following licensed plugins inside WHM/cPanel: Softaculous for one-click scripts, Imunify360 for automated malware defence, and WHMReseller to let me create tiered reseller plans. On top of that, I want the typical safety and convenience add-ons in place: • CSF (ConfigServer Security & Firewall) already tuned with the cPanel profile • MailScanner configured to start automatically and scan all queues • Let’s Encrypt so every new account can issue free SSL with AutoSSL I don’t need unusual tweak...
I need a skilled developer to turn the Nihrika Kaladev concept into a fully-functioning piece of software. The core request is straight software development—no web or mobile layer at this stage—so your focus will be on architecting, coding, and testing the main application itself. The exact operating system is still open; I’m happy to hear your recommendations on whether Windows, macOS, Linux, or a cross-platform approach would serve the project best. Whichever route we take, clean, well-documented code and a straightforward build process are essential. Deliverables • Compiled application ready for end users • Complete, human-readable source code held in a private repository • Setup / installation guide and brief user manual Please outline the techno...
