I build backends that hold under load, and I teach machines to help people learn.

The spark

At Rwanda Coding Academy I found out that I like knowing how things work all the way down: the circuit, the kernel, the query plan.

Break it to understand it

Reverse engineering taught me to read other people’s systems before I trust my own. Our team took first place in the high school division of picoCTF Africa.

Into production

Then real users. Visitor check in, e-commerce, a national registry interface. I learned that tests, schemas and boring migrations are what keep a system alive.

NestJS with TDD, 85%+ coverage
Spring Boot and RabbitMQ
PostgreSQL tuning, 40% less lag

Built to scale

Today I run backends where latency is the product: live driver tracking, a wallet ledger, notification gateways that process more than ten thousand actions a day.

PostGIS geospatial indexes
WebSockets in real time
Kubernetes at 99.9% uptime
Query latency down 35%

Teaching machines to teach

Now I build AI that has to be right. UWERA is a tutor for Rwandan students, grounded by retrieval so it answers from the curriculum, not from its imagination.
