Azmain, the chonkdev.

Fullstack engineer obsessed with high-performance backends, event-driven microservices and the kind of clean architecture that ages well. I write TypeScript, Python & Go for a living — and Vue/Nuxt when the frontend asks nicely.

About

I'm a fullstack engineer who treats backend code like it's going into production on a Friday afternoon — because it usually is. My happy place is designing event-driven microservices, taming gnarly business logic and making databases sing.

Over the last few years I've shipped ERPs running across 9 sister concerns, built a food-delivery platform stitched together with Kafka and gRPC, and kept a South-African logistics engine humming through 3,000+ daily tracking events.

I care about Hexagonal Architecture, DDD, and the boring discipline of writing code that future-you (and your teammates) will actually enjoy reading.
