Engineering scalable solutions for a global impact.

About

A bit about who I am and what drives me.

I am a Senior Software Engineer with a passion for architecting high-performance, enterprise-grade applications. Currently at Griffin Global Technologies, I drive the development of complex full-stack solutions using ASP.NET Core and React.js, collaborating with high-performance engineering teams across Kenya, Ethiopia, and the USA to deliver world-class products.

Previously a Tech Lead at Pesira Technologies, I combine deep technical expertise in cloud-native architectures with a strategic, results-driven mindset. I thrive in high-velocity Agile environments where clean code, scalable infrastructure (AWS/GCP), and exceptional user experiences are the standard. My goal is to build software that doesn't just solve problems, but empowers businesses to scale.
