Andrew Ambuka

@andrewambuka

AI integration engineer at SokoFresh connecting SokoPay payment workflows and backend services.

At SOKOFRESH, I build and maintain backend services for SokoPay payment processing and inventory operations. I reduced API latency by 40% through Redis caching and backend optimization, and improved automated test coverage from 0% to 85%.

I also contributed to the SOKOPAY SYSTEM and built an offline-first paramedic triage app with synchronization and retry handling. My work spans REST APIs, payment and reconciliation workflows, and SMS/WhatsApp and email integrations.
