Production fintech backend for Diba — wallet transactions, payment processing, and real-time chat. Delivered well enough that the same team brought me back immediately for a second, larger platform.
A fintech startup needed a production-grade backend capable of handling wallet-based transactions, secure payment processing, and real-time communication between users — all with the financial security and reliability that live money movement demands.
Built a comprehensive Django backend with PostgreSQL for data integrity, integrated payment APIs for transaction processing, and implemented Django Channels with WebSockets for real-time chat features. Used DRF for API standardisation with layered JWT-based security across all financial endpoints.
Currently live in production at diba.africa, handling real financial transactions. The same engineer who managed the project brought me on immediately to the next platform (10 Billion), which is the clearest signal of trust.
"I worked with Andrew on the Diba Fintech API, and he was a great asset to the team, consistently delivering high-quality work with strong attention to detail."
