From 36,259 reviews, clients rate our Debugging Experts 4.9 out of 5 stars.I run a complex System-on-Chip project and reserve about four hours each week for focused progress. During that window I rely on an experienced engineer who can jump straight into SystemVerilog / UVM code and keep our verification flow tight. The core of the session is SoC-level development, yet every task circles back to solid design-verification practice: • Testbench development that plugs cleanly into our existing UVM environment • Live simulation and debugging, spotting corner-case failures as they appear • Coverage analysis and closure so we meet functional goals with data-driven confidence Remote pair-programming over a shared workspace works best for me; I’ll have source, waveforms, and spec documents ready before each call so we can spend the full four...
(edited) This is a freeware Windows-based desktop application which has stopped working properly because several server links inside the code are now invalid. I believe SQLITE was used for the application or part of it. The program either crashes or simply fails to continue once it tries to reach those outdated endpoints. Your task is to trace every call that relies on these links, repair or replace them, and confirm that the whole application runs smoothly again on current Windows builds. You will receive the existing files. I did not create this program so I do not have the full project "source code." This program is designed to search using isbn or the title of a book. It returns marc data (.mrc) files from open source libraries. I can provide a demo showing this program wor...

Please provide a clear project timeline, milestones, and estimated cost.
I’m looking for an experienced Chrome Extension / JavaScript developer to complete and improve an existing Manifest V3 browser extension. The project already has a solid foundation with a dashboard, profile/account management, saved form data, Chrome Storage, background service worker, runtime messaging, API integrations, import/export, payment-related UI, status and printing modules. The main work is to review the existing code, understand the architecture, fix incomplete or broken functionality, improve the UI and data flow, implement a secure license-key authentication system, and make the extension stable and production-ready. Please do not rebuild from scratch unless technically necessary. Experience with Chrome Extensions, Manifest V3, JavaScript, Service Workers, Chrome APIs, ...
Overview: Qgen Engineering is a US-based hardware and software company. We're looking for an experienced electrical engineer to perform an independent design review of four board designs before we commit to fabrication and volume builds. This is a review engagement — no layout, firmware, or redesign work required.

I run , a WordPress-WooCommerce store for LDV car parts. Stock control is handled with the ATUM Inventory Management plug-in and payments go through the TYL banking gateway. Lately, confirmed buyers hit “Place order” only to meet a technical/server error and the transaction stalls. No payment is captured, no WooCommerce order is created, and our stock levels stay unchanged. The error messages appear in the browser and in the WooCommerce logs, so we know it’s not a silent failure—yet my part-time techs haven’t been able to trace the root cause. Here’s what I need: • Diagnose why WooCommerce is blocking or timing-out at checkout. • Pinpoint whether the fault lies in the theme, the ATUM plug-in, TYL’s API, or server configuration (PHP...
I need a skilled React developer to jump into my existing code-base and complete a new feature from concept to merge-ready pull request. The exact area—whether state management, hooks, or a UI component—will be clarified as soon as you come aboard, but you should be comfortable working across a typical modern stack that includes React 18, functional components, and JSX/TSX. Here’s how I picture the collaboration: • First, you review the current repository, ask any clarifying questions, and outline a concise plan for the feature. • Next, you implement the solution in clean, well-commented code, following our linting rules and component structure. • Finally, you supply a PR with passing unit tests and a short hand-off note so I can verify, merge, and de...
# Freelance OJS Developer – Fix Left Sidebar Links We are looking for an experienced **Open Journal Systems (OJS) developer** to fix an issue with the left sidebar navigation links on our journal website. ### Task The OJS website has a left sidebar containing several navigation links. Some of these links are pointing to the wrong journal path/domain. For example, links are currently being generated with: `/` but they need to point to: `/` The issue should be fixed properly at the **OJS/theme/template level**, rather than relying only on a temporary JavaScript workaround. ### Requirements * Strong experience with **OJS (Open Journal Systems)** * Experience working with OJS themes, templates, PHP, HTML, CSS and JavaScript * Ability to identify where the incorrect URLs are bei...
On every product page of my Shopify store the main images slide down and cover parts of the description, price, and add-to-cart area. I need the underlying CSS / Liquid adjusted so each product image sits neatly in its container, no longer overlaps any text, and stays that way on desktop, tablet, and mobile. You’ll work directly in the theme (Online Store 2.0) or supply the exact code snippets with clear placement notes—whichever is faster for you and safer for version control. I can open a collaborator account the moment we agree. Acceptance criteria: • All product images render without touching or covering any text or buttons. • Spacing remains consistent across every published product page. • Changes survive theme updates; no hard-coded hacks that brea...
I am looking for an experienced developer to take over and improve an existing working web application called PosterForge. The project already has its main functionality implemented. I am not looking for a rebuild from scratch. The goal of this project is to: clean up the existing UI/UX so the application is simpler, clearer and easier to use; review and test the functionality that has already been implemented; identify bugs, unreliable behaviour or poorly implemented features; correct and improve those areas where necessary; tidy the existing code where appropriate; ensure the main workflows work consistently and reliably. When the project is returned to me, I want the functionality that has already been started to work properly and reliably, with a much cleaner and easier-to-use inte...
I’m Daniyal Ashar, a third-year Bachelor of Computer Applications student, and most of my current coursework is in Python. I’m looking for someone who can walk me through the language in a practical way—answering questions as they come up, reviewing the code I write, and showing me the best practices that lecturers often skim over. Expect a mix of conceptual discussion and hands-on problem solving: some days I may bring an assignment that refuses to run, on others I might want to explore how a particular library works or how to structure a small personal project. Clear explanations, clean sample code, and constructive feedback are what I value most. If you’re comfortable tutoring Python at an undergraduate level—debugging, refactoring, or simply breaking...
My Revolution Slider has suddenly vanished from the front-end after I installed a new plugin. The slides, images, and navigation simply don’t render—just empty space where the slider should appear—while the rest of the page loads as usual. Nothing else on the site was changed, so I’m convinced there’s a conflict introduced by that recent installation. I need someone who can jump in right away, trace the conflict, and bring the slider back without disrupting any other part of the site. Your job is to: • Diagnose why the slider is not displaying (conflicting plugin, script error, outdated Slider Revolution version, or server setting). • Apply the fix—whether that means adjusting settings, modifying code, or isolating the offending plugin&mdas...

I have a custom integration that keeps Total Synergy and Trello in sync through their public REST APIs. Lately, I’ve spotted dates drifting out of alignment, so the immediate objective is to pinpoint where the sync is breaking down – I’m not chasing speed improvements yet, just accuracy. Your task will involve: - Checking that the webhooks are functioning properly based on the required functionality. - Analyzing and ensuring accurate database syncing between Total Synergy and Trello. - Debugging any issues you uncover with explanations provided. This is a one-time fix. However, if your work is excellent and meets expectations, there is an opportunity for another job within the same system involving changes and further debugging. Deliverables: • Ensure all noted di...
My in-house Chrome extension suddenly refuses to load at all—no icon, no background processes, nothing. I need an experienced extension developer to step in, pinpoint the cause, and restore full functionality. You’ll get access to the current source (manifest v3), the last working build, and a short screen-capture of the failure in Chrome 125. If third-party conflicts or API deprecations are involved, I’d like a brief note so I can avoid repeating the problem on future updates. Deliverables: • Diagnose and document the root cause of the “extension not loading” issue. • Supply corrected code and a compiled .crx or unpacked folder ready for testing. • Confirm the fix works on the latest stable Chrome for Windows and macOS. No UI red...
I’m getting ready to spin up a prototype and need an experienced PCB designer to turn my schematic into a clean, single-layer board that will end up larger than 10 cm × 10 cm. I’ll provide the circuit diagram along with a few placement preferences; from there you’ll handle footprint selection, component placement, manual or auto-routing (whichever gives the most reliable results on a single copper layer), and all the usual design-rule checks. Because this is strictly for prototyping, I’m less worried about space savings and more concerned with trace clarity, manufacturability, and easy debugging. Standard through-hole parts dominate the BOM, but a couple of SMD footprints may appear—nothing exotic. If you normally work in KiCad, Altium Designer, or Eagl...
I need a seasoned electrical / electronics engineer to take a voltage stabilizer for industrial equipment all the way from concept to a bench-tested prototype. The unit must accept anything from 200 V to 480 V on the input side. What I am expecting from you: • A complete schematic with component selections that balance reliability and cost. • Simulations (LTspice, PSpice or equivalent) that verify thermal behavior, transient response and overall regulation. • PCB layout files (Altium, KiCad or similar) ready for fabrication, with clear creepage / clearance and EMI considerations. • A detailed bill of materials, including alternative parts in case of supply issues. • Assembly and test procedures so I can replicate your bench results and move to pilot produc...
I need a test engineer who can run comprehensive manual functionality tests on a mobile application before its next release in Singapore.

This assignment centers on programming and configuration within Siemens TIA Portal, with the sole focus on PLC programming for an S7-1200 family controller. I will provide the I/O list, functional description, and any existing tag tables; the task is to turn those documents into a clean, fully commented project that compiles and runs without errors. Key activities include building all required OBs, FCs, and FBs, structuring data blocks for readability, and handling basic diagnostics. If you prefer PLC-Sim for initial validation, that is perfectly acceptable and remote testing access can be arranged afterward on the real hardware. Deliverables • TIA Portal project file (.ap17 or earlier on request) • Annotated source code with English comments • Exported tag list in X...
I’m extending an existing cross-platform mobile application and need a seasoned developer who is comfortable shipping the same experience on Android and iOS. The core tasks I’d like you to tackle next are: • Local scheduled and repeating notifications that persist reliably across both operating systems. • Speech-to-text for two distinct use cases: quick voice-note capture and real-time voice commands. • Text-to-speech with a choice between standard system voices and richer AI-generated voices. • Full Firebase wiring—email / social auth plus push notifications. • Razorpay-based payments, covering one-time purchases and renewable subscriptions. • Thorough testing and debugging on real hardware (not just simulators) before we submit t...

I need a seasoned C/C++ developer to craft a Direct Memory Access application that runs reliably on Windows. The core requirement—beyond solid performance and stability—is an integrated automatic-update system so users never have to reinstall manually. We can cover the finer technical points one-on-one over Discord or email, but in broad strokes here is what will move the project forward: • A fully working Windows DMA executable written in C/C++ • An update mechanism that checks, downloads, and patches seamlessly • Clean, well-commented code that future developers can extend When you reply, please include: – A couple of DMA-related or similarly low-level projects you have completed – Your estimated timeline (no hard deadline on my side,...
I need a front-end developer who can jump into my existing React codebase and repair the mobile layout. On both iPhone and Android handsets the homepage, all product/service pages, and the contact/info section lose their structure—columns collapse in odd places, spacing and alignment go off, and certain components spill past the viewport. Tablet view looks fine, so the issues appear confined to phone-sized breakpoints. You’ll be working in plain React (no ) with styled-components controlling most of the presentation. I’ll grant repository access and a staging link so you can test changes in real time. My expectation is concise, standards-based CSS or styled-components updates—ideally using flexbox/grid tweaks and media queries rather than heavy rewrites. Deliverab...
