About
Mobile-focused Software Engineer with 5+ years of experience who built a fintech app from zero to 1.3K+ users, shipped apps for a national utility company, and delivered products across Ghana and the US. Strongest in Flutter with full-stack reach into Node.js, React, and Firebase.
I build mobile apps with Flutter and Kotlin, web apps with React and Next.js, and backend services with Node.js — from fintech platforms to delivery systems and logistics apps.
Based in Kumasi, Ghana, I work with international teams to ship production software across the full stack.
