I’m updating the quiz page on my corporate website and need a developer who can focus strictly on functionality.

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.

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...

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 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’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 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.

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, ...
