// what i do

I take your SaaS from napkin sketch to production — without the dev-team drama.

Autonomous technical partner for non-technical founders and C-suite executives. Fixed-price milestones. Zero-bloat architecture. Singapore-incorporated entity for enterprise trust.

You've been burned by developers who:

  • Overpromised and delivered a nightmare — I've fixed those messes
  • Ran up bloated $500/month AWS bills — I build on $40 Hetzner stacks
  • Owned the hours but not the outcome — I own the architecture, delivery, and production

// how I deliver

🛡️ 14-Day Alignment Guarantee Not a fit? Full refund within 2 weeks. No questions.
⏱️ Async-First Execution One weekly sync. Everything else via text/Loom.
