Before rolling it out wider, I need a full round of QA to be sure that every click, screen and background process behaves as expected. Scope of the test • Cover functionality end-to-end: install, login, project search, bid submission, notifications and auto-fill features. • Evaluate the user interface: layout, wording, icons, colour states, and any responsive behaviour when you resize or switch devices. • Measure performance: load times, CPU/RAM spikes, lag on high-volume projects and any impact on overall browser speed. Environment Run the extension on both desktop and laptop hardware. I need separate passes on Windows, macOS and Linux, each using the latest st...

I’m rolling out a new GST application and need a qualified GST practitioner or CA to validate it in carefully planned phases. The focus is exclusively on the reporting module—returns filing and reconciliations are the priority. Here’s how I see the engagement working: • At the start of each phase I’ll share the feature set (GSTR-1/3B flows, purchase vs. sales reconciliation, etc.) along with access to the staging environment. • You’ll run real-world scenarios, verify every field against current GST rules, and stress-test edge cases that practitioners encounter day-to-day. • Any variance in tax computation, mismatch handling, or portal-ready JSON must be flagged with clear replication steps, screenshots, and your professional recommendat...
I need a Quality Engineer who can sit beside me a few hours each week in Tampa and help validate our finance-sector web applications. You will split your time between hands-on manual exploration—walking through new features, drafting edge-case scenarios, logging defects—and building lightweight automated checks so we do not repeat the same regression work sprint after sprint. Because most day-to-day conversation happens in Telugu, and key requirements come from stakeholders in Hyderabad, I am specifically seeking an Indian engineer who speaks Telugu fluently. Local presence in Tampa is essential; remote or out-of-country arrangements will not work for this role. The ideal collaborator already knows Selenium (or a comparable WebDriver framework) and feels comfortable wirin...
I run all of our asset intake through a Fusion scenario that feeds directly into Workfront Classic, but the upload path does not parse the data when uploaded. I need someone who already lives and breathes Workfront and knows exactly how Fusion should be configured to step in, regain control of the upload management flow, and chase down the root cause of those errors. Here’s what I’m looking for you to do: • Review the existing Fusion workflow that handles the uploads, map each module, and spot mis-configurations. • Fix whatever is causing the current system errors so every file in a test batch lands in the right project without manual retries. • Fine-tune the overall upload management process so it runs reliably and, if possible, a bit faster. • Leav...

My production site runs on the React JS on the client, a Node.js/Express API, and MongoDB for persistence. After an external audit with another freelancer I now have a clear list of security weaknesses and several functional bugs that escaped earlier testing. Most of the issues sit in server-side logic: exposed endpoints that bypass auth checks, insecure data validation, and some race-condition edge cases that crash certain requests. On the client, a few components render unpredictable states after failed API calls, so error boundaries and tighter state management will need attention as well. I will share the exact findings (code snippets, Postman collections, and a short Loom walkthrough) at project start. All fixes must be applied directly to the production branch via fork-and-PR so I...

I maintain a JavaScript/Node.js web application built with React and one feature has started misbehaving. I will provide the repository link, clear steps to reproduce, the current versus expected behaviour, and any relevant environment details. Your task is to reproduce the issue, isolate its root cause, deliver a concise fix that touches only the code involved, and verify the result with a test or other reproducible check. To keep things tidy I need: • the corrected code committed to the existing branch • a test or manual verification script that proves the fix works • a brief summary (one-paragraph release note or commit message) outlining what changed and why Please let me know how quickly you can turn this around when you respond.
Canada citizen only. This is a remote contract role, and candidates must complete a background check and employment history verification. I have an RTL block, chip or SoC described in SystemVerilog that now needs full functional verification. All verification work must follow UVM, from environment architecture through coverage closure, so that results can be maintained and extended by the in-house team once the contract ends. Scope of work • Build or adapt a complete UVM environment around the supplied DUT, including sequencer, driver, monitor, scoreboard and any passive agents needed for interfaces already defined in the spec. • Develop constrained-random and directed sequences that exercise every item in the functional specification, aiming for 100 % functional and line c...
I’m looking for a freelancer who can help me perform SW updates to the Automotive Audio Amplifier. The parts are not in the vehicle and are located in El Paso.

I’m looking for someone to test several small apps on physical Apple devices and record short demonstration videos for App Store review. Each app supports either iPhone or Mac, so it only needs testing on its supported platform.

## What you'll do We're building a new web app that helps people hire freelancers. We want honest first-time feedback from someone playing the **client**: the person with a job to get done. The practice copy is being finished now. We'll award once it's ready, and right after award you'll get a private link to your own **practice copy** of the app in chat. The freelancers in it are simulated, so no real jobs are posted and no money moves. Use a **desktop browser** (laptop or desktop, not a phone). ## The script (about 2 to 3 hours) 1. Start a project from your own one-line idea of something you'd want done. 2. Answer the questions the app asks you, then change one thing in the plan it proposes. 3. Post it. 4. Read the candidates and open a conversation with o...
The Vineta plugin on my site breaks its intended functionality every single time it runs. Core actions refuse to execute, throwing fatal errors and blocking users from completing tasks. I need a developer who can dive straight into the Vineta codebase, trace the root cause of these always-present issues, patch them cleanly, and verify the fix across current WordPress (6.x) and PHP (8.x) versions. Please work directly in my staging environment, make upgrade-safe changes that follow WordPress standards, and document every adjustment so I can keep the plugin maintainable long-term. Deliverables • Clean, fully tested source files with the functionality bug resolved • Clear, step-by-step changelog explaining what was fixed and why • Confirmation that the updated plugin in...
I need a thorough performance review of my website focused strictly on load testing. The goal is to understand how the site behaves when real-world traffic spikes hit three critical areas: the home page, the checkout process, and the user login/register flow. I expect clear metrics on response time, throughput, error rates, and bottlenecks as traffic scales upward. Feel free to use the load-testing stack you’re most comfortable with—JMeter, Gatling, k6, Locust, or a comparable tool—as long as the final report explains your methodology, virtual user profiles, test scripts, and raw results. Deliverables: • Test plan detailing scenarios and expected load levels • Executable scripts or configuration files • Summary report with charts, key findings, ...

I have a live DeFi DApp running on Ethereum and I need thirty real Web3 users to put it through its paces. Each tester must connect a wallet, complete several buy-and-sell transactions, explore every screen, then tell me exactly where the experience shines and where it breaks down. Here’s how the process will run smoothly: • You secure thirty unique, verifiable users who are comfortable with Metamask (or any standard EVM wallet) and have a small amount of ETH for gas. • Every tester goes end-to-end: wallet connect → buy token → sell token → confirm settlement on-chain. • While moving through the app, they note UX friction, unexpected gas spikes, UI glitches, and any confusing language.
