I built payment infrastructure for Emergent Payment, including a centralized middleware ecosystem for the University of Professional Studies that unified student data, wallets, billing, disbursement, PSPs, and banks.
Using Node.js, PostgreSQL, Redis, Docker, and AWS, I delivered an 87% reduction in student billing complaints, 45% faster bill generation, and eliminated PSP-side reconciliation errors. I also built a multi-tenant church USSD engine and a cashout platform supporting fast bulk, individual, and recurring mobile-money payments.
At Ashesi University, I developed AI and data projects for African contexts, from a Twi-focused image translation system to a water-shortage prediction model covering 261 districts.
