What I'm looking for

I’m open to remote roles worldwide and very willing to relocate.

At Turing, I built RAG search for athlete data, so users can ask questions in plain language and get answers only from records they’re permitted to see. I tested prompt and retrieval changes against real user questions, and led a platform redesign onto microservices, Kubernetes and Docker.

I also moved a core service from AWS to Google Cloud, cutting running costs by 15% while maintaining 99.9% uptime. I wrote shared permissions and logging components for other teams, mentored junior engineers, and worked with product to set requirements.

Earlier, at Teledeus Limited and Afrits Innovation Limited, I moved legacy systems to microservices and built banking, school management, e-commerce and VAT aggregation software. I also designed and launched Naija Republic, a live multiplayer 3D game, during a week of leave using AI coding agents and strict test gates.
