What I'm looking for

I’m looking for a backend role where I can own end-to-end delivery, build reliable APIs and async systems, and continuously improve performance—shipping production-quality features with strong engineering collaboration.

I’m a backend engineer with 4+ years building scalable, high-availability systems across fintech, health-tech, and e-commerce. I design robust APIs, async workflows, and database-optimised backends that serve thousands of users.

I’ve consistently shipped production systems end-to-end—from design and documentation through deployment, monitoring, and continuous improvement. In my work, I emphasize “you build it, you run it ownership,” especially when reliability and developer velocity matter.

At Reliance Health, I led backend development and launched Alafia, a retail health insurance platform, owning the full lifecycle from design and documentation through deployment and monitoring. I authored complex, optimised SQL queries to surface actionable insights for customer support and shipped critical bug fixes that improved application reliability.

Previously at OneRoute, I designed failover server architecture for critical APIs, improving availability by 50%, and built cross-platform chatbot infrastructure that reduced agent-routed issues by 75%. I also refactored backend code to optimise database query performance and eliminate memory leaks, boosting server efficiency by 62%—while driving measurable reductions in customer complaints.
