I've led full-stack delivery at Black Diamond Store, building payment tracking, client management, reporting, and financial analytics features for a unified business platform.
I designed RESTful APIs and a Node.js/TypeScript Excel processing engine that converts spreadsheet data into structured payment records, reducing manual processing time by up to 60%. I also established Docker and GitHub Actions CI/CD pipelines, automated testing, and production logging.
At Shaper, I improved the MTN Ayoba Developer Portal by redesigning Node.js and Express APIs and optimizing PostgreSQL queries, cutting average API latency by 45%.
I've also improved Ayoba Marketplace checkout, increased micro-app onboarding completion by 40%, and delivered commercial web applications independently from architecture through deployment and client communication.
