De 108,699 opiniones, los clientes califican nuestro Testing / QA Specialists 4.9 de un total de 5 estrellas.I operate a live online betting platform and want a qualified ethical hacker to run a full-scale penetration test against the public-facing web application. The priority is website & application-level weaknesses, so I expect you to probe everything users can touch: signup, log-in, wallets, odds display, live bets, admin panels behind authentication—every feature that might be exploited. Please include the usual suspects—SQL injection, XSS, CSRF, IDOR, authentication bypass, file upload issues, business-logic flaws—essentially the OWASP Top 10 and anything else you uncover during your manual and automated reconnaissance. Black-box testing is preferred at first; if you later need limited credentials for deeper inspection we can arrange that. Deliverables I need: &bull...
I need to put my production-grade web server through a rigorous workout and would like you to design and run stress tests in both JMeter and k6. The goal is to see how well the server copes with heavy concurrent user load, high data throughput, and the inevitable spikes that push response times to their limits. I already have staging and production endpoints ready; what’s missing is a well-structured test plan, clean scripts, and a clear report that turns raw numbers into actionable insights. Here’s what I expect from our collaboration: • Test plan that explains the scenarios you will model, the target traffic profile, and any assumptions you make. • JMeter (.jmx) and k6 (JavaScript) scripts parameterised so I can rerun them myself later. • A run book desc...

My iOS and Android app is ready for a full workout and I want that workout to be fast, repeatable, and easy to re-run whenever a new build drops. Local emulators are my preferred environment because they let us iterate quickly, though I’m fine if you spin up BrowserStack or Sauce Labs for edge cases you can’t reproduce locally. Functional coverage is the top priority, but I also expect you to observe usability quirks and keep an eye on possible regressions from previous versions. The outcome I’m after is a clean, well-documented defect list that leaves no doubt about how to reproduce each issue. Deliverables I’ll review: • A concise test plan outlining device profiles, OS versions, and scenarios • Execution logs and screenshots (or short clips) that ba...
I have a mobile application that must be exercised end-to-end through simulation tools on both iOS and Android. Your task is to run functional, usability, and regression passes inside popular device clouds or local emulators—whatever gives me fast, repeatable coverage—then report every issue with clear evidence. I expect you to: • spin up a representative range of iPhone and Android devices in BrowserStack, Sauce Labs, Xcode Simulator, Android Studio Emulator, or any similar environment • walk through all core user stories, deliberately probing edge cases, interrupted states, orientation changes, and network shifts • capture screen recordings or screenshots, logs, and precise reproduction steps for every defect • retest after fixes to confirm closure...
I have several models of home routers that must be exercised on the US networks of Spectrum, Comcast, and AT&T. The work centers on three concrete tasks: running thorough speed tests, executing broadband dial-up procedures, and pushing stability sessions Most measurements can be conducted in your testing environment; I only need occasional remote access so my R&D team can dive into log captures or anomalies while they are fresh. Deliverable • A concise test report (PDF or DOCX) that maps each scenario to its outcome, includes raw metrics, screenshots or log excerpts where helpful, and highlights any failures or deviations from spec. The assignment is complete once that report is in hand and I can trace every data point back to the underlying scenario.

I am building a new solar-hybrid inverter around an Infineon reference design and need an experienced technical advisor who can work with me on-site in Bangalore, part-time, through the entire prototype cycle. Your guidance is required across hardware design, firmware development, hardware fabrication, integration and final testing.

Expect plenty of hands-on lab work—oscilloscopes, power analyzers, thermal cameras, rework stations—plus...

Looking for a QA Tester to test a web application that manages product syncing and inventory operations.

Please document each defect with steps to reproduce, screenshots or screen recordings where helpful, and a severity rating so I can triage quickly. A concise summary report and the raw test logs (if you capture console or network data using standard browser dev tools) will complete the engagement. I will be availa...
I’m running a 14-day closed test on Google Play and need exactly twelve unique Android users onboarded through my invite link. You’ll share each tester’s Gmail address so I can whitelist them. They must be from real devices. Here’s the flow I have in mind: once you’ve assembled the group, send a joint introduction email—copying me—so I can distribute the invite. Testers simply need to accept the invitation, install the app, and keep it on their phones for the full two-week period. There are no demographic or location requirements; any Android smartphone user is acceptable. Verification is straightforward. On day 1 collect an installation screenshot from every tester, and on day 14 capture a fresh “still installed” screenshot. If anyo...

I need a reliable partner who can deliver twelve Android smartphone users for a closed Google Play test. The testers have to accept my invite link, install the app, remain opted-in for the full 14-day period, and open the app from time to time so usage analytics register correctly. I will handle all coordination with the testers directly by email; once you’ve sourced them, copy me on the first message so everyone stays in the loop. If anyone opts out early, please swap in a replacement within 24 hours so the group stays at twelve active users for the entire window. What I expect from you • Identify and onboard 12 unique Android smartphone testers • Supply each tester’s Gmail address so I can add them to the Google Play list • Confirm installation scre...

We operate a continuous stream of thousands of user-generated files for an Enterprise client, and each item must clear a strict quality gate before it is released. The submissions arrive as photos, screenshots and .eml files. Your role is to inspect every asset against the client-supplied guidelines, approve or reject it, and document the decision clearly. Most files come in a mix of languages. The visual, structural and privacy rules remain constant, so you should be comfortable switching contexts, spotting issues even when the text is unfamiliar, and flagging anything that feels uncertain. For photos and screenshots you will verify resolution, legibility, metadata accuracy and that no sensitive personal data slips through. In the .eml files you will also confirm full header integrity, ...
