Mihai Serbanescu

@mihaiserbanescu

Software Development Engineer in Test at vestr AG who built its Playwright and TypeScript automation suite.

At vestr AG, I introduced structured QA processes and built an end-to-end test automation suite from scratch in Playwright and TypeScript for a React-based trading and portfolio platform. I integrated automated tests into GitLab CI/CD and GitHub Actions, replacing largely manual feature testing.

I own regression, smoke, feature and migration testing for releases, and report QA KPIs and release quality to product and management. I also investigate defects using Chrome DevTools and GCP logs, and hold ISTQB CTAL-TAE and CTFL v4.0 certifications.
