What I'm looking for

I’m seeking a senior contributor role focused on backend architecture, API design, and high-quality software delivery.

At edgeDX, I’m the primary hands-on contributor to backend architecture for a distributed healthcare platform. Android field devices collect diagnostic data offline and sync it to central servers and health ministries across Nigeria, Ethiopia, and Kenya.

I’ve developed Spring Boot integration services and REST APIs for the device fleet, and worked on database administration and DevOps. Through freelance work, I’ve also delivered custom Shopify apps and supported GCP, Linux, and MySQL operations.
