👋 Hi, I'm Serdar

QA Engineer based in Chemnitz, Germany 🇩🇪 — open to relocation

API Testing · UI Automation | Java · Selenium · REST Assured · SQL

Currently automating API and UI tests for a Spring Boot + MySQL application at UpTeam GmbH (Berlin, project-based since Apr 2026). Background in IT infrastructure & networking (Cisco, Linux, VPN) — I bring a systems-level perspective to QA: I think in terms of network layers, JWT lifecycle, HTTP-level debugging, and CI/CD environments.
