I'm a full stack developer specializing in local payment integrations, Chapa, M-Pesa, and Telebirr, for businesses across Ethiopia and East Africa. I've shipped a Flutter app live on the Google Play Store, plus four other production platforms including a multi shop ordering system with WhatsApp integration that real shops use daily. I work across the MERN stack, TypeScript, and PostgreSQL, from database design to deployment. If you need payments working reliably in the East African market, or a full app built from scratch, send me the details and I'll tell you exactly how I'd approach it.
