Teams hiring junior QA testers
Worth noticing
The listed toolkit spans Playwright and TypeScript, Postman and SQL, plus devices including a Flipper Zero, ESP32, and Raspberry Pi.

Field notes

The portfolio breaks the tester’s work into callable tasks, including tracing root causes through PHP, Apache, and server logs, then writing reproduction steps. Its system inventory names both everyday tools such as Ubuntu and Postman and hardware such as an ESP32-S3 and Raspberry Pi. The page also connects its testing approach to earlier game modding, PC repair, business operations, and production incidents.
