About Me

Mathews Mwangi

Mathews Mwangi

Backend Engineer

Port Louis, Mauritius

The story

I build systems designed to stay alive under continuous load — GPS telemetry pipelines, event-driven backends, real-time data fan-out at scale.

Most of my work started with a problem I felt directly. Alebus came from standing at a bus stop in Mauritius for 45 minutes with no idea when the next bus was coming. Lakazhub came from watching people navigate long-term rentals entirely through WhatsApp groups. I find a problem, understand the domain, and build from architecture through to production.

I work primarily in Go for backend systems and have been going deep on distributed systems — Kafka, Kubernetes, gRPC — as the natural next layer of what I build.
