I'm a software engineer based in Nairobi, Kenya 🇰🇪. I focus on building reliable, AI-powered backend systems and mobile products with a philosophy centered on simple, transparent, and high-performance infrastructure.
I currently work at Seismic as a senior backend engineer.
I run Bytes Lab, an indie studio where I design, build, and ship software products. It's where I do my most technically ambitious work — from architecting multi-service backends to crafting iOS apps and getting them to the App Store.
An uptime API monitoring platform built for indie devs who hate bloat. Built around async Python workers, Redis and NATS, I implemented:
- Custom Scheduling: Built entirely on Redis sorted sets.
- Real-Time Updates: Leveraging Redis PubSub for instant UI fan-out.
- Incident Notification Delivery: Utilizing NATS for high-reliability notification streaming.

I’m always open to collaborating on high-stakes projects—whether it’s architecting a high-performance backend, designing a scalable REST API, or crafting a fluid iOS experience. If you have an idea that requires a focus on reliability and performance, let's talk.
