What I'm looking for

I'm looking to build reliable, high-scale backend and full-stack products, especially in payments, banking, data-driven applications, or AI, while partnering closely with product, operations, compliance, and client stakeholders.

At Prime Circle Finance, I lead the Python/Django payment-orchestration backend routing transactions across multiple providers for 25+ business clients in 30 African countries.

I built transaction processing and reconciliation systems with PostgreSQL and Celery that handle 100,000 payments a day at 99.7% reliability, reducing manual reconciliation from two hours to 15 minutes.

Previously at Community Dental Partners, I delivered a missed-appointment prediction model that lifted attendance by 40%, automated healthcare-record transfers for 95% of patients, and improved collections processing efficiency by 60%.

I've also built AI-powered WhatsApp banking features processing 5,000+ weekly transactions, along with API, payments, and Chrome extension projects. I enjoy translating operational and compliance needs into dependable production systems.
