Hi, I'm Eren. I studied Software Engineering and now work as a QA engineer on mobile app monetization testing (subscriptions, paywalls, purchase flows). On the side I build backend and test automation projects.
Tools I use: Python, Go, C#, TypeScript, Dart/Flutter, pytest, Playwright, FastAPI, Flask, Firebase, SQL, Docker, GitHub Actions
- lol-draft-assistant: champion select assistant that suggests picks and bans from the live draft state (FastAPI, React, Tauri, SQLite).
- paywall-lab: a Go subscription/paywall backend with a QA automation suite (pytest API and contract tests, Playwright E2E).
- CanEmAll-Coop: unofficial online co-op mod for Can 'Em All (BepInEx, C#).
- talkbetter: Flutter + Firebase app for 30-second mock interview practice with AI corrections.
- claude-code-failover: hands a Claude Code task to another agent CLI when a turn fails or hits a limit.
- epub-translator-en-tr: command-line EPUB translator (English to Turkish) that keeps the book's formatting.
