As a freelance Full-Stack Web Developer, I build responsive websites and web apps for remote clients, from prototype to deployment. My work includes KHANIMAMBO, a professional-services PWA, and a loan and finance management system for Mutsape Microcrédito.

I integrated the Vodacom M-Pesa production API for MK Pictures and built an AI automation connecting a website to OpenAI and WhatsApp for customer replies. Previously, as IT Manager at Provincial Directorate of Transport and Communications (DPTCI), Inhambane, I administered Windows Server and managed network infrastructure.
