About Me
Full Stack Software Developer — Nairobi, Kenya
3+ Years Building Production Systems in Kenya and East Africa
I'm a Full Stack Software Developer based in Nairobi, with hands-on experience building and supporting fintech, payroll, ERP, property management, and e-commerce systems. Most of my work sits at the intersection of backend complexity and real business problems.
I work primarily with Laravel and PHP 8+ on the backend, React.js and Next.js on the frontend, and Flutter/Dart for cross-platform mobile. I deploy to VPS and cPanel environments, use Docker for local and staging setups, and I've administered ERPNext/Frappe deployments in production.
