At Biometric s.r.o., I designed a Playwright and TypeScript test system from zero for two production SaaS products and their supporting systems. Regression releases went from about two days to under an hour, and a nightly suite ran 166 times in a row without flaky failures.

At Brehon, I designed a four-agent MCP orchestrator that validates around 80% of features before human QA. I also built and run my own LLM job-search assistant; my evaluation harness measured an increase in CVs with no invented facts from 70% to 89%.
