Hi, my name is

Nimrod Nyongesa

I architect full-stack systems that think — LLM-powered backends,
autonomous agent pipelines, and the frontends that make them usable.
5+ years shipping production code from Nairobi.

> about

I'm a fullstack engineer and AI systems builder based in Nairobi, Kenya. I spend most of my time at the intersection of backend architecture and AI — building autonomous workflows, RAG pipelines, and LLM-powered tools that replace manual processes.

When I'm not wiring up agent orchestration, I'm designing API-first backends that handle payments, geolocation, real-time delivery, and async job pipelines. I connect these to interfaces people actually want to use — SPAs, mobile apps, and real-time dashboards.

My philosophy: if it's not automated, it's not done. I GitOps everything, containerize deployments, and instrument with proper observability. I also occasionally go down rabbit holes with Rust, WebGL, and low-level systems programming.
