Available for work Kampala, UG
Full-Stack · Product Developer
I build digital products for the African market — Mobile Money, marketplaces, SaaS, and offline-first apps — pairing thoughtful design with solid engineering.
S1 — Featured work
Real applications, shipped end-to-end — from fintech and SaaS to offline-first tools built for the African market.
S2 — About
I'm a full-stack and product developer based in Kampala. My work is tuned for the realities of the African market: Mobile Money as the default way to pay, expensive and unreliable data, and users on affordable Android phones. I build products that respect those constraints instead of fighting them.
I ship end-to-end — product thinking, interface design, backend, integrations, and deployment. I can take an idea like “help boda owners confirm daily lease payments” and carry it all the way to a working app that matches a Mobile Money transaction to the right rider and confirms it within seconds.
I lean on modern AI tooling across the whole workflow — prototyping, content, and delivery speed — and I've built several products where AI is the core of the experience. Same goal every lap: useful software that's fast and reliable for the people actually using it.
