About

Full-stack engineer with 15+ years building web applications, SaaS platforms, game infrastructure, and cloud systems. Founded companies, shipped games on Steam, built platforms that got acquired.

Strong work ethic. I take ownership, ship fast, and get things done. AI-native developer using Claude Code and Cursor daily.

Working Style

  • I learn any stack in days, not weeks
  • MVP in weeks, not months
  • Give me the problem, I'll solve it
  • Lead or IC, I ship either way
  • Async-first, overlap with US, EU or APAC
