I need native smartphone users currently located in Belgium, Taiwan, Colombia, Argentina, France, Mexico, Chile, or Spain to run a round of functional tests on our dual-service mobile application. The job is straightforward: First, install the latest build on both iOS and Android devices you own. Create a new account so I can verify that user registration works smoothly in each market. Next, move on to the two core journeys—booking a ride and ordering food. Complete each flow from start to finish, including payment (we provide promo codes so you will not be out of pocket) and cancellation where relevant. While testing, note every screen, button, message, and edge case that behaves unexpectedly or feels confusing, capture screen recordings or screenshots, and collect basic device lo...

We ship new features every few days, so quality must keep pace. The task is to own end-to-end testing - both manual and automated; from designing cases right through to signing off each release. Manual coverage is expected on functional flows, user-experience quirks and full regression sweeps. At the same time, a lightweight Selenium suite should be expanded (or created if gaps exist) so that smoke tests run automatically inside our CI pipeline. Project Overview Own the full QA lifecycle for cutting-edge Agentic AI products. We're seeking a sharp, self-starting QA pro who thrives in dense environments, finds bugs lightning-fast, and delivers fixes without handholding. Weekly releases demand speed: hit 90% critical path coverage in 21 days, regressions under 10 minutes, and bug-free...
Our engineering organization is doubling down on shift-left quality, and the next milestone is a fully automated test suite that lives alongside the codebase and runs on every commit. The work spans strategy, hands-on coding, and mentorship. You will craft an automation framework in Selenium, writing suites in Python, Java, and JavaScript—whichever language best fits each micro-service. Functional coverage comes first, followed quickly by performance scenarios that exercise real-world concurrency and data volumes. Each suite must plug into our existing CI/CD pipeline so that failures block the build and generate actionable reports for developers inside their pull requests. Key targets include: • Converting current manual regression cases into reliable Selenium scripts. &bu...

I need a fully-functional Google Voice account for 10 Users supported, registered from India but tied to a U.S. phone number, so I can place and receive personal calls to and from the States. The account itself does not yet exist and I have not picked a number, so part of the job is guiding me through—or handling—the selection of an available U.S. number that feels natural to me. Because Google Voice is officially unsupported here, you’ll have to take care of the usual hurdles (VPN, verification SMS to a real U.S. mobile, billing profile if required) and then hand over a clean login that I can secure with my own 2-step authentication. I plan to use the service interchangeably on both my smartphone and my laptop, so please configure and test calling on the Google Voice mo...
I need a cyber-security professional who specialises in application security to review and harden a production-ready mobile app that runs on both iOS and Android.

We will meet in short, focused sessions (screen-sharing preferred). Between calls I will try the ste...
