What I'm looking for

I'm particularly interested in solving complex backend problems, improving system reliability, and building scalable products in fast-moving engineering teams.

At Innovastra, I contribute to Tamiin, a healthcare payer platform, where I implemented Claims Financing workflows for Payables, Settlements, and Adjustments. I also integrated Paystack payments, including webhook validation.

On Tamiin, I applied CQRS and event-driven communication across backend services and optimized SQL Server queries, schemas, and stored procedures. I also contributed configuration-driven backend functionality to OneCare, an EHR platform.

Previously, I built backend services for REChops using ASP.NET Core and Entity Framework Core, then containerized and deployed them with Docker and Kubernetes. At Bethema Skincare, I developed GraphQL APIs for order, logistics, and dispatch operations.
