Hiren Thacker

Associate Director of Engineering · Bangalore, India

I build the systems and the teams that ship them.

15 years from individual craft to engineering leadership — across fintech, healthtech, and marketplaces. Hands-on roughly 80% of the time, on purpose.


What I'm working on

  • Shipping an AI-native micro-drama React Native app — leveraging Claude Code with custom skills for TDD and structured requirement gathering
  • Designing the eng-leadership chapter of my career around teams that combine craft (TDD, pairing, code review) with AI-assisted velocity
