## About

```text
At a leading Pan-African payments and agent-banking fintech, I took an inbound payment transfer service from an empty repo to production and built settlement flows that handle millions of daily transactions without discrepancies. I also developed automated recovery for abandoned deposits, saving more than 100 operations hours monthly.

At Sterling Holding Company, I led backend architecture for a core banking platform processing over two million daily payment transactions, with 99.9% uptime. I cut customer alert latency to under 100ms with a Kafka notification engine and recovered 65% of API response time under peak load.

At Google (via Turing), I evaluated LLM-generated code and autonomous agent behavior, then built validation pipelines and prompt improvements to reduce hallucinations and improve reliability. Across my work, I’ve focused on secure, reliable payment systems and practical engineering improvements.
