    Important - Please read before submitting your proposal: To ensure smooth communication, applicants must possess advanced or intermediate English proficiency. U.S. residents are preferred. While in-person meetings are ideal, remote work is also possible for experienced developers. Due to previous developers' unclear identities and lack of contact, applicants must quickly familiarize themselves with the ongoing project to ensure development proceeds without interruption. Before the project begins, our technical team will conduct a brief test. Those who pass the test will participate in a 30-minute technical interview. As this project involves currently operational systems and sensitive infrastructure, you must present a valid identification document, such as a passport or driver's...

    I need an experienced mobile-app professional to stress-test AppForge—the AI Android app generator linked below—and tell me, with evidence, how far I can realistically rely on it for real-world business software. The task is strictly evaluative; you will not be asked to code anything by hand. I will hand over a handful of representative business app briefs and give you access to the production targets AppForge supports (Base44, Lovable, and FlutterFlow). Your job is to push the tool to its limits, document where it succeeds, where workarounds are acceptable and where it flat-out blocks progress.

You will own the entire test cycle for each build, running functional, usability and performance passes across the current browsers and devices we support.

    I have a small web-based application that needs its security posture checked right away. The goal is to build an automated suite that performs penetration-style tests each time the app is deployed, flagging anything that could be exploited before it reaches production. Scope – The work is limited to security testing; I do not need functional or performance checks at this stage. – Within security, the emphasis is on penetration testing methods: automated discovery of common weaknesses (SQLi, XSS, auth bypass, misconfigurations) and clear proof-of-concept steps. Tech expectations Python with Selenium, Playwright, or a comparable headless browser tool is fine, and I’m open to OWASP ZAP or similar APIs if that speeds things up. Please wire the tests so they can be tri...

    We need an experienced manual QA tester to thoroughly test a live, already-deployed web app called PriceMatch and produce a clear bug report. ABOUT THE APP PriceMatch lets a customer log a purchase they made at a retailer (Best Buy, Costco, Target, Walmart, Amazon), then automatically tracks that product's price. If the price drops within a 60-day window, the app alerts the customer by email/push so they can claim a price-match refund from the store. It's a React web app (also installable as a PWA) backed by a Node.js API. WHAT NEEDS TESTING 1. Account & login - Register, log in, log out, change password - Stay logged in across browser sessions/tabs — confirm you are NOT unexpectedly logged out during normal use (this was recently changed, please test carefully) - Ed...
