Founder & software engineerSingapore, SG1.3521° N, 103.8198° EGMT+8 · --:--:--

I'm 19 and I build systems that robots, banks and thousands of people rely on. Right now that's RAVN, self-healing infrastructure for robot fleets, where I'm the lead engineer.

My systems follow one rule: a model proposes, fixed rules decide, and a person approves what matters. I've shipped 60+ products from Addis Ababa that way.

Building, and open to hard problems. Come say hi.

RAVNLead Engineer

Self-healing infrastructure for robot fleets.

1 yr 9 mo

2025 - Present · part-time

  • Built the backend and AI workflow for a platform that turns plain-English hardware descriptions into schematics, PCB layouts, firmware, BOMs and fabrication files.
  • AI proposes designs, fixed checks test electrical and physical constraints, and people review the result.
  • Built a minimal 3-tool interface (instruct, autonomous_instruct, check) so external AI agents can operate a robot without low-level hardware commands.
  • Integrated Digi-Key, Mouser, LCSC, JLCPCB and PCBWay; grew to 4,000+ users with enterprise letters of intent.
  • Accepted into Antler with RAVN.
