Work

What I've built, and what it cost

Production platforms with real traffic and real money moving through them. Three case studies go deep on the engineering; everything else is listed honestly.

Also shipped

Other platforms on the same stack

Backend, payments and streaming work. Same architecture, same markets — listed without a case study because the engineering story overlaps with the three above.

Open source

Things I build on my own time

Personal repositories — mostly Go backends, and one offline-first mobile app for a problem I couldn't stop thinking about.

paramedic-triage-intake

Offline-first React Native app for paramedic patient intake and triage. Built for ambulances where connectivity drops mid-transport — records queue locally and reconcile on reconnect.

  • React Native
  • Offline-first
  • SQLite

Ticketing-BE

Go backend for a ticketing platform. Event and seat management, ordering flow, and the concurrency handling that stops two people buying the same seat.

  • Go
  • PostgreSQL
  • REST

LMS

Learning management system backend in Go. Courses, enrolment and progress tracking with role-based access across students, instructors and admins.

  • Go
  • PostgreSQL
  • RBAC
Open to full-stack / backend roles

Got a system that needs to hold up under real traffic?

I'm looking for full-stack and backend roles where the hard part is the load, the latency or the money moving through it. Happy to talk through anything you're building.
