Kenya

Message

At Griffin Global Technologies, I build services for an event exhibition transportation project, handling shipping and logistics requests with C#, React, PostgreSQL, and Docker. I also built BFF services that tailor data delivery between backend microservices and the React front end.

On the same company's event management platform, I led backend development for room, session, and file workflows. I also designed and maintained an application with C#, Angular, and Azure that improved file accessibility by 30%.

At Smart Applications Group Ltd, I programmed a full-stack alert management system that improved service delivery by 20%. I also streamlined integration APIs for multiple clients and implemented monitoring dashboards with Grafana and Prometheus.

Earlier, I improved internal platforms, integrated third-party APIs, and developed reporting tools at Stepwise Africa Inc. My experience also includes software development at Empire Microsystems and Jochrison Capital Ltd, along with freelance work through Upwork.
