At Wildberries, I scaled a frontend function from 1 to 8 engineers, created three autonomous domain units, and helped three engineers become unit leads. I lead distributed teams with structured processes that keep delivery reliable without overtime.

I led a monolith-to-microservices and independent-packages migration that accelerated releases by 20%, while overhauling code review and knowledge-sharing practices to reduce critical bugs by 40%. I also built end-to-end YouTrack workflow automation and introduced user-flow testing that reduced regressions by 38%.

Earlier, I migrated 15+ legacy codebases to React 18, developed seller portal features serving 15M+ monthly sessions, and improved supplier workflows for 500,000+ sellers. I combine React and TypeScript depth with mentorship, team health, and sustainable engineering culture.
