At Safaricom PLC, I lead backend development, maintenance, and integration for Digital Business Hub microservices using Spring Boot. I also delivered Business Connect, a bundled digital solution for SMEs, from development through integration and ongoing maintenance.

At Telkom Kenya, I built the Subscription Manager platform in Spring Boot for SMS subscriptions, handling approximately 1.6 million requests per day. I also developed integrations between internal and partner systems and deployed APIs on Telkom's API Gateway.

Earlier at Telkom Kenya, I deployed APIs supporting internal systems, supported airtime purchase services, and monitored the 777711 Paybill platform. I also generated transaction and performance reports for stakeholders.

At Symbiotic Media Consortium, I maintained an internal Laravel e-commerce platform and contributed to development and QA testing of Safiri Express. I hold Oracle Cloud Infrastructure and IBM Cloud certifications, along with certifications in network security and Oracle Database PL/SQL.
