At Estuary Business Solution, I build and maintain production APIs for food ordering, events, ticketing, and apartment booking. I also designed a multi-vendor cart and order system to reduce fulfilment conflicts, and automated vendor disbursements through Paystack.
For EBSPay, I built a multi-provider payments and bill-collection API covering Flutterwave, MTN MoMo, and Interswitch. I made wallet operations atomic and added automatic refund recovery, webhook security, and background workers for payment updates.
I created SHOW, a pay-per-view African film and live events platform, as its sole owner of architecture, code, and infrastructure. Its 16 Go services support verified, idempotent payments, DRM-protected video, and live interactive rooms; a flash-sale change cut seat-hold p95 latency from about 750 ms to 95 ms with zero overselling.
