I need my entire stack—both the web application and its companion mobile builds—moved from the current server to a fresh hosting account. I already hold full credentials for the existing environment, so you will have immediate access to download everything you need. The mobile apps are not store-hosted; they have been built, downloaded and installed locally, so please allow for any extra packaging or configuration those binaries may require once the back-end is relocated. While migrating, I also want a careful security sweep. The previous developer had full control and I want confirmation that no hidden users, cron jobs, backdoors, hard-coded keys or other forms of silent access remain in the codebase, databases or server configuration.

# One-Time Deployment of Lovable WhatsApp Reminder App ## Project Overview I have built a personal productivity application using Lovable. The application helps me manage contacts, schedule reminders, and send WhatsApp messages at selected times. The application is already developed, and the source code has been pushed to a private GitHub repository.

I want all five of my staff to start using professional, domain-based Gmail accounts while keeping our current domain intact. Your job is to handle the full Google Workspace setup, point the MX records correctly, and make sure each mailbox is up, tested, and secure with 2-step verification. Alongside email, please switch on the essentials we’ll actually use—shared calendars, Google Drive file sharing, and basic contact groups—so the team can collaborate right away. I’m still undecided about migrating old mail; build that option into your plan and let me know the extra steps or tools involved so I can choose before we go live.

Nexara Labs USA is looking for a principal-level backend engineer who wants something bigger than another short freelance ticket. We already have a live platform, CRM workflows, quoting logic, affiliate attribution, sales infrastructure, internal tools, and real operational users.

I’m planning to roll out a small-footprint Identity and Access Management editor that my clients can use to create, view, and adjust their own policies without touching the underlying infrastructure. At its core the tool should let an administrator sign in, browse existing users and groups, and then add, change, or revoke permissions through an intuitive interface. Although I have not finalised the target environment yet, I want the architecture to stay flexible enough to plug into common cloud stacks such as AWS, Azure, or Google Cloud later on. If you already have presets or libraries that handle role definitions, access-control statements, or audit logs for any of those platforms, feel free to mention them in your approach. The deliverable I’m looking for is a working ...

I need my Ubuntu droplet on DigitalOcean fully hardened and served behind Cloudflare SSL. Your first task is to configure Cloudflare so the site loads over HTTPS without warnings; Full or Full (Strict) is fine as long as it’s end-to-end encrypted. Once SSL is sorted, lock the server down. SSH is the only exposed service, so it must be bullet-proof: key-only logins, non-standard port (if practical), root login disabled, fail2ban (or similar) in place, and an automatic e-mail that alerts me—showing IP, user, date, and time—every time someone successfully authenticates. Complement that with: • UFW/iptables rules limiting inbound traffic to the essential ports. • Unattended security updates. • Log rotation and basic integrity checks (e.g., Lynis report or equ...

Build a secure web-based background verification platform Like Verify24x7 that allows an authorized user or organization to request a person's court/criminal-record verification. The platform should search available lawful court/public-record sources, identify potentially matching records, verify the identity match using the information provided by the requester, and generate a clear verification report. The system must distinguish between: - No matching court record found - Case found / pending - Case disposed - Acquittal/discharge where available - Conviction where officially recorded - Record requiring manual review - Unable to verify The application must never automatically label a person as a criminal merely because a case/FIR/complaint appears in a database.

I need my existing website rebuilt from the ground up so it mirrors the current content and structure yet outperforms it in search rankings. The copy, images and overall page count will stay the same, but every template and asset must be refreshed into a modern-looking, fully responsive layout with a noticeably smoother user interface. Throughout the rebuild, on-page SEO is the main driver. Clean code hierarchy, fast load times, schema markup, accessible HTML5/CSS3, and well-structured meta data all need to be baked in from day one so rankings can climb the moment we flip the switch. Google Search Console and Analytics integration should be part of the launch checklist. Security comes right after SEO. The finished site must safeguard user privacy, protect any stored data, and include...

I need a full-featured matrimonial site tailored to one specific state. The core flow is straightforward: visitors register, their photo is cleared through automated verification software, they pay a yearly membership fee, and they can then search for matches using an extensive set of filters. Key functions to build • Registration with e-mail / mobile OTP, automated photo authentication, and an admin queue for any doubtful images. • Secure payment gateway that charges a single, renewable yearly fee and records all invoices in the admin panel. • Powerful search: caste, tribe, religion (these are non-negotiable), spoken language, mother tongue, education, occupation, siblings, physical measurements, present and permanent addresses, marital status, and medical history.

I need a concise, practical set of coding rules that zero in on secure-by-design practices. The end product should read like an internal standard any developer on my team can pick up and apply immediately, regardless of project size or framework. What matters most to me is clarity and real-world applicability: guidelines that flag common attack surfaces, prescribe safe patterns, and illustrate both “do” and “don’t” examples. Feel free to draw on OWASP, MITRE, or other respected references if they strengthen the reasoning, but every rule must be expressed in my own organisation’s plain language so it slots straight into a living style guide. Deliverables • A structured rules document (Markdown or Google Doc) covering secure coding practices from ...

I’m looking for a fresh, expert set of eyes on my already-launched SaaS. The priority is a thorough check of both Security and Performance. I’ll share the exact tooling, checklists, and testing methodologies I currently use so you can step straight into the review process without guessing which scanners, profilers, or penetration-testing suites to run. Here’s how I see the engagement unfolding: you explore every security layer—from authentication flow to data storage—and benchmark performance under realistic load. When you’re done, I’d like a concise report that highlights the key findings, high-impact risks, and the quick wins that will give me the most immediate improvement. No need for a long-form narrative or slide deck; a sharply written summ...

I need a secure, clinician-facing web application that lets authorised prescribers create a digital prescription, apply a legally valid electronic signature, and transmit the order straight to my GPhC-registered pharmacy for tracked-courier fulfilment. Primary users will be general practitioners and independent prescribers, who need to create an account and have their licence verified before being able to prescribe. The flow should be simple—search or add a patient, create a prescription, sign, and click “send”. Behind the scenes the platform should store an immutable audit trail, maintain patient records, and push the signed prescription to the pharmacy via secure API (FHIR, HL7 or a custom JSON schema—happy to discuss the best fit). Key requirements • Dig...

About the project We are building, a legal practice management platform designed specifically for small UK law firms. The product has been founder-built and has now developed into a substantial application. It is already well beyond prototype stage, but it has reached the point where I want an experienced senior engineer to review the architecture, challenge previous decisions, identify technical risks and help establish a maintainable engineering direction. This is not a greenfield project and I am not looking for someone to rewrite the application from scratch. I am looking for someone who is particularly good at inheriting existing systems, understanding them quickly and deciding what should be kept, simplified, improved, removed or deferred. Current technology The application is ...

Financial Literacy & Lead-Generation App — Project Description Overview We are building a mobile-friendly application for a bank that helps everyday users understand insurance products and other financial instruments (savings, investment, and protection products) in a simple, friendly, and multilingual way. The app is educational and lead-focused: users learn about products, get their questions answered by an AI assistant, and can submit an enquiry that is routed to the bank's sales/agent team for follow-up. This is a non-transactional platform — no purchases, payments, or account opening in this phase. Goal Improve financial literacy, present the bank's products in an accessible format, and generate qualified leads — while giving the bank full control to ...

I need architect advice for a no-code/configurable enterprise SaaS currently under development. It will have multiple modules, with each module purchased separately. Please advise on: 1. Multi-tenancy: Should we use Hybrid Multi-Tenant architecture? Compare shared DB/schema, separate schema, separate DB and hybrid approaches considering GxP, security, scalability, performance and cost. 2. Customer/Site model: A corporate customer may have 10+ branches/sites, each with different electronic processes. Should the hierarchy be Customer → Sites → Modules → Processes → Users? Should sites be separate tenants, sub-tenants or part of one tenant? 3. Environments & DB: Each customer may require DEV, VALIDATION and PROD. For a customer with 10+ sites: - How many DBs are r...

MVP Build — Quote Request We're looking for a freelance developer or small team to quote an initial MVP build. This is a rough-scope request to get a ballpark quote — not a full technical spec. Additional phases/tiers will be scoped separately once we're underway.
