About

Backend engineer working on payments and geospatial systems in startups. Built a mobile-money (M-Pesa) pipeline with idempotent reconciliation for a banking platform serving 2,000+ smallholder farmers, migrated a production database to PostGIS for farm plot geometry, and built flyt.africa end to end — flight search through issued ticket, FastAPI/Postgres/Kafka on AWS with Terraform and 330 tests, Next.js on the front end.

Looking for: backend or full-stack work on systems where correctness matters — payments, fintech, geospatial, or agriculture and climate data. Open to full-time or contract. Most interested in joining a team with real code review, after two years of building largely on my own.
