From 131,920 reviews, clients rate our Software Testers 4.9 out of 5 stars.My e-commerce site runs, but the moment I touch anything related to product management things break. I am dealing with clear functionality errors: creating a new item, editing an existing one, even basic inventory moves sporadically fail or show wrong data. I need someone who can step into the codebase, trace the offending logic, and deliver a clean, tested fix so every product-related action behaves exactly as intended without introducing fresh issues elsewhere in the checkout flow. Deliverables I expect • Root-cause diagnosis of the product-management malfunction • Clean, commented code or configuration changes applied in my environment • A concise report outlining what was wrong, how it was fixed, and how to avoid the same pitfall in future updates Please be ...
I need a handful of freelancers who already work in Pipedrive on a daily basis to help me validate a brand-new Pipedrive app before its public roll-out. The task is simple but stretches over a few weeks: • install the app in your live Pipedrive account, • keep it running while you go about your normal pipeline, contact and email activities, • experiment with it in as many real sales situations as you can, and • leave an honest review in the Pipedrive Marketplace once you have solid, experience-based feedback. Please tell me your rate for this multi-week test, confirm that you are an active Pipedrive user, and outline the approach you would take to stress-test the app (e.g., number of deals you touch, frequency of use, any edge cases you plan to cover). Clear,...

Hi All, I am looking for a developer who can design and develop a UI that can place and manage orders directly in my Zerodha trading account. The key requirements are as follows: The UI should monitor the Nifty Futures LTP and place 2–3 orders based on predefined conditions. Once the orders are placed, they should be displayed at the bottom of the UI. The UI should provide an option to modify the existing orders. There should be an Exit All button to close/cancel all active orders. The interface should be simple, user-friendly, and responsive. Integration with the Zerodha trading account/API will be required. Please let me know if you have any questions or require further clarification regarding the requirements. Thanks & Regards, Naveen
I have a small MacOS-only project already packaged as a .zip. When the user opens it, two consecutive pages appear and the same button must be pressed on each page before the flow can continue. I want that step removed from the user journey: the button has to be clicked automatically, on both pages, without any extra input. The target is straightforward: • Detect the page load, • Locate the identical button (its selector/identifier is the same on both screens), • Fire the click event twice—once per page—so the process moves forward exactly as if the user had pressed “Continue”. Any approach that works natively on MacOS is acceptable—AppleScript, Swift with the Accessibility API, a lightweight shell/osascript wrapper, or an embedded automation ...
My team and I have taken the “Eyerus ayalkibet” project all the way through initial research, planning, design, development, and an initial testing pass. We now need a fresh set of expert eyes to complete the remaining quality-assurance work.

What I need from you: 1. Conduct comprehensive functionality testing across all user flows, including sign-up, account management, and core feature interactions. 2. Perform detailed UX testing—look for confusing navigation, inconsistent UI elements, or anything that breaks the user...
I need a seasoned QA professional to run a thorough manual sweep of my entire website. The focus is three-fold: first, verify every user-facing screen for visual or functional defects; second, probe the backend workflows and API responses to be sure data is handled exactly as intended; and third, look for obvious security vulnerabilities—things like broken access control, unprotected endpoints, or input that isn’t being sanitised. All testing will be done from a desktop environment, so please cover the current versions of the major browsers (Chrome, Firefox, Edge, Safari) on Windows or macOS. What I expect from you • A structured test plan outlining the scenarios you will cover before you begin. • Clear, reproducible bug reports with screenshots or short scree...

I want to push our resume-parsing engine to its limits by feeding it deliberately tricky files. I will send you a clean résumé in plain text; your job is to engineer multiple adversarial versions of it—both DOCX and PDF right from the start—using every document-level sleight of hand you know. Hidden text, layered images covering text, font or glyph substitution, OOXML rewrites that mis-align the visual and logical order, even extraction quirks that only show up when the file is flattened to PDF: anything that could fool an ATS should appear somewhere in the series. I am flexible on tooling—Python, C#, or a mix—so choose whichever lets you script the generation process cleanly and document it for repeatability. The end goal is twofold: realistic files ...
I need an experienced automation engineer (around 4-10 years working with Playwright in both JavaScript and TypeScript) to build and maintain a solid test suite for my web application. Scope • Target platform is strictly Web. • The suite must run reliably on Chrome and Firefox—cross-browser parity is essential. • Coverage spans all three layers: end-to-end flows, critical integration points, and a handful of fast unit tests around our helper utilities. Day-to-day you will wire Playwright into an existing Node/TypeScript repo, design a clean folder structure, and implement sensible fixtures, mocks, and test data factories. The code must be readable, reusable, and commit-ready with meaningful assertions and screenshots on failure. I will also rely on you to add...

I’m looking for an experienced C++ developer who is comfortable working in a Linux environment to track down and resolve a functionality bug that’s affecting one of my applications.

I am building a focused construction project-management web app whose top priority is accurate planning and scheduling. The core workflow will let me create projects, break them into tasks, and set clear task-to-task dependencies so the entire timeline adjusts automatically when something moves. Beyond the scheduling engine, I also need a lightweight equipment-tracking module. It should let me assign cranes, loaders, generators, or any other site equipment to individual tasks, flag date conflicts, and produce a daily allocation report. No labour or material tracking is required at this stage, so the interface can stay streamlined around equipment only. Key expectations • Task-dependency scheduler that supports critical-path logic and instantly recalculates dates. • Visu...

I need a sharp-eyed GoHighLevel specialist to jump in and straighten out a handful of misbehaving automations. The most urgent pain point is tag management— some contacts are picking up the wrong labels, while others get none at all—so your first task will be to audit every tag rule, make corrections, and confirm the right tags fire at the right stage. Beyond that, two things are breaking the experience: certain workflows refuse to trigger when they should, and a few older automations appear to be clashing or duplicating actions. I’d like you to trace each workflow from opt-in or payment through to the final email, remove or merge anything that conflicts, then run end-to-end tests to prove everything now fires cleanly. Deliverables: • Corrected tag logic applied ac...

I need help bringing a large, legacy learning-management system—well over 50,000 lines of plain PHP 5.5—up to PHP 8.5. The application was written without any framework, and there are currently no automated tests in place, so great care is required to safeguard existing behaviour while removing deprecated syntax and functions.
