Backend Engineer at Appnable building microservices and REST APIs for production products.

Nigeria

Message

At Appnable, I design and deliver backend services, from REST API design and database schema modeling through production release. I build microservices with Node.js, Express.js, and TypeScript.

I also optimize database queries, indexing, and server-side data-processing pipelines, and define API contracts with frontend engineers to keep integrations reliable.

At Uri Creative, I designed and built Uri Academy's sales platform end to end, including its database, backend APIs, and responsive React interfaces. I also built conversational lead-generation features that help the sales team identify and prioritize high-intent prospects.

Earlier, I integrated Paystack and Flutterwave payment gateways and built OAuth authentication at Bejite. At Qucoon, I developed responsive React interfaces and integrated RESTful APIs.
