What I'm looking for

I'm looking to build reliable, scalable financial or customer-facing platforms, with meaningful ownership across APIs, transaction systems, modern web applications, and high-volume integrations.

I've built banking, lending, PAYGO, and e-commerce products across KCB Bank, Badili Africa, Omnivoltaic Energy Solutions, and Paylend Africa. My work spans transaction processing, payment workflows, customer onboarding, and operational platforms.

At KCB Bank, I built Java Spring Boot services integrated with core banking infrastructure and implemented event-driven financial integrations with Apache Kafka and RabbitMQ. I also supported KYC/AML workflows, IPRS identity verification, and containerized deployments using Docker and OpenShift/Kubernetes.

Previously, I developed React and TypeScript customer experiences alongside Node.js APIs for smartphone commerce, solar financing, and digital lending. I focus on reliable financial systems, scalable APIs, and practical platforms that support customers and operations teams.
