I build distributed and scalable Python / Django systems serving millions of clients.

5+ years at Savannah Informatics. I shipped the health-insurance exchange linking 7 insurers and 2,500+ providers, then moved onto the digital health infrastructure behind Kenya's universal health coverage programme, SHA.

THE STORY SO FAR

I'm a backend engineer who cares about reliability, observability, and architecture that's safe to change and scale

For five years I've built and led production Python/Django systems in health-tech. That includes multi-tenant platforms, data pipelines processing millions of records daily, and API integration and identity layers holding it all together. I drop into Rust and Golang for the performance-critical paths.

I follow proper TDD with pytest and prefer a written RFC before significant code changes. I currently lead a product engineering team of six, and work best with real ownership in async-remote environments.

Selected work

7 insurers · 2,500+ providers

Slade360 EDI

Led the product engineering team of six building a health-insurance Electronic Data Interchange serving 7 private insurers and 2,500+ providers across Kenya — later extended into the national claims infrastructure behind the country's universal health coverage programme. Architected a multi-tenant, white-labelled extension with OAuth2/OIDC to kick off a West Africa expansion.

Luna — Moon Phase Indicator

A GNOME Shell extension showing the current moon phase in the top bar — phase, illumination, distance and lunar age computed locally with the Julian Date algorithm, no internet required. Published on extensions.gnome.org with 2,800+ downloads.

Live vessel tracking

AIS Tracker

A maritime intelligence platform in Go, running as one binary against one Postgres instance. Streams live AIS vessel positions over a WebSocket feed, detects port calls, geofence crossings and dark-vessel gaps, and surfaces it all on a Leaflet map — pushing Postgres into PostGIS, TimescaleDB, pgvector and CDC territory.

Price-time priority

Thande Stonks Exchange

A continuous matching engine written in Rust: per-symbol engine shards over tokio channels, a BTreeMap order book with price-time FIFO matching, a 4-check pre-trade risk pipeline, write-ahead-log + Postgres trade persistence, and a real-time WebSocket market data stream. 70 tests, benchmarked, Dockerised.
