At Karamelion, I architected and built the backend for an AI document intelligence platform, serving web, mobile, and admin clients through a versioned REST API. I developed document retrieval pipelines and model routing with structured-output validation, fallbacks, and citation grounding.

At Benmore Technologies, I delivered production applications across AI, fintech, and enterprise, and reduced monthly infrastructure costs by 42%. I also solo-built and deployed NDVS, the national identity system for Nigerian law students, which has onboarded 820+ students.
