Not a CV, and not a list of jobs. These are the three things I am proudest of - each one shipped, measured, and recognized by someone other than me.

01

Cut QA execution time by 60% with agentic AI at MOSTLY AI

Introduced agentic QA in August 2025, before agent frameworks went mainstream: a 24/7 agent (LLM + Playwright + Jira) that turns natural-language requirements into executable test suites, plus AI-driven validation for synthetic-data generation - at a GenAI company, where the bar for “AI that actually works” is the product itself.
