About

I’ve been online since 1999, got my first paid coding gig in 2003 during college, moved into my first full-time developer role in 2007, and launched my first self-started startup in 2009. I work best in small teams and build reliable services end-to-end — from API design to production ops.

How we can work together

  • I ship products end to end: from architecture and backend to frontend and release.
  • Engagements: partner/co-founder or long-term contract.
  • I specialize in backend and ground decisions in product and UX; I can handle frontend and simple mobile apps as needed.
