At SpeedPay Finance Limited, I build and maintain RESTful APIs for a live fintech product, including payment gateway and KYC integrations. I containerized the application with Docker, reducing environment-related failures by around 40%.

On MatchMetric AI, I built a real-time resume optimizer that compares resumes with job descriptions and streams AI feedback to users. I also built EasyTransact, a fintech wallet with payment integrations, security features, and automated savings.
