Innovative and detail-oriented Full-Stack & Mobile Software Engineer with extensive experience designing and developing scalable solutions across Android, iOS, Web, and Backend stacks.

Skilled in Flutter, Kotlin, Java, Swift, TypeScript, Vue.js, Node.js, Laravel, and Java Spring Boot with strong focus on FinTech, SACCO systems, MPesa integrations, USSD menus, WhatsApp chatbots, and enterprise-grade backend systems.

I build complete end-to-end solutions: mobile apps → backend APIs → USSD flows → automated background workers → WhatsApp bot integrations.

"To use my full-stack and mobile engineering expertise to deliver secure, scalable, and high-performance software across financial, communication, and enterprise systems."
