I designed, built, and operate SONKA, a live freight marketplace for Tele-Port Prime Ghana Ltd. I built its Node.js/Express backend, Postgres/Supabase data layer, React Native apps distributed across four Android stores, Next.js operations dashboard, and live Paystack and MTN mobile-money payments.
I also run fourteen n8n workflows in production and use AI coding tools with a security-first review process. I audit generated code for silent failures, test payment edge cases adversarially, and recently found and closed an exploitable Postgres data exposure involving driver contact, vehicle, and live GPS data.
