Mathenge Newton

I've built production platforms at Ujuzi Code, including Sideways' corporate shuttle dispatch system, which supports 10,000+ corporate trips per month, and Jimcab's corporate taxi dispatch workflows. My work spans Fastify, NestJS, PostgreSQL, Redis, BullMQ, WebSockets, SMS, GPS, and client-facing reporting portals.

As Founder and Lead Developer at Mango Season Labs, I architected SIMS for Sideways employers and delivered retail, restaurant, e-commerce, and driver-app products for clients including UzaX, Tosha City, LakeTown, and Magicomputers. I build end to end: backend APIs, React and Next.js dashboards, React Native apps, background workers, testing, and Docker deployments.

I've also built .NET money-movement and agency-banking services at Fintech Group Kenya, reviewed AI agent code changes at Turing, and mentored 50+ developers through TechCamp Kenya. I enjoy clear technical communication, code review, practical architecture, and helping distributed teams ship reliable products.
