Case study: Gowthamora Testing Arena
A live QA and SDET interview quiz at testing.gowthamora.com. Scenario questions across manual, automation, SQL, API, performance, data and AI testing, with every answer explained and sourced. First commit 11 Sep 2026; 115+ commits since.
How it is built: TypeScript, React, Express 5 and PostgreSQL. Questions come from a reviewed bank of about 280, with AI-assisted generation behind a server-side proxy so keys never reach the browser. Every question passes strict server-side validation and duplicate detection. Source code is private.
How it is tested: 90+ Playwright end-to-end tests in 13 spec files (auth, roles, security, resilience, navigation, cookies), run in GitHub Actions CI with trace reports, plus a load test and a live-site probe workflow.

I spend time with a new tool every day and ship one build each weekend. Dated entries, only what I can show.
