About Me

Senior Frontend Engineer and Team Lead with 11+ years in software development, including 5 years leading a development team.

I build products across the full spectrum: from complex enterprise web apps and Electron desktop clients to Telegram bots, browser games, embeddable widgets, and mini-apps. I care about clean architecture, performance, and shipping things that actually work.

  • Current role: Team Lead / Senior Frontend Developer
  • Team experience: Leading and mentoring a frontend team, code reviews, architecture decisions, sprint planning
  • Philosophy: Pragmatic engineering — right tool for the job, no over-engineering, ship fast and iterate
