At Cellulant Kenya, I build high-performance RESTful APIs and unified payment network interfaces using Java, Spring Boot, Quarkus, and Laravel, helping simplify partner integrations.
I've developed Kafka and RabbitMQ event-driven systems, implemented JWE/JWS encryption, request signing, authentication frameworks, and STRIDE threat modeling for secure payment products. My experience spans checkout APIs, merchant onboarding, API integration support, internal systems, WooCommerce plugins, testing, monitoring, and performance optimization across Africa.
