What I'm looking for

I seek roles where I can lead test automation and performance efforts, work in fast-paced financial or enterprise teams, integrate testing into CI/CD, and grow into senior quality engineering responsibilities.

I am a hands-on Software Development Engineer in Test with a .NET backend background, focused on building reliable, maintainable test automation using Playwright and TypeScript. I drive automation for financial and IAM systems, optimizing E2E suites, reducing regression execution time, and integrating tests into CI/CD pipelines.

I also design and execute performance tests with k6, maintain test-suite health by fixing flaky tests and implementing API fixtures, and collaborate closely with developers to ensure system reliability. I bring practical cloud and backend experience from .NET development, database optimization, and migration work to improve overall quality engineering outcomes.
