I've built Laravel, Filament, and mobile systems for Gilanis Distributors, Kytabu, CoAmana, and Software Technologies. At Gilanis, I delivered GatePass logistics modules, an internal Filament portal, M-Pesa payments, and Acumatica ERP workflow automation.

I've owned features from database design through deployment, reduced API response times by 40% at Kytabu, and built offline-first Flutter applications for agricultural markets. I also mentor junior developers, conduct code reviews, and create secure systems using JWT, OAuth, and RBAC.
