01 / About
I'm a Nairobi-based Full Stack Software Engineer with 8+ years of experience building everything from IoT data platforms and fintech infrastructure to mobile apps and SaaS products. I co-founded Qwerty Systems — a software studio focused on turning ideas into polished digital products.
Currently at Polariks (Bosman Van Zaal), I build smart agriculture and industrial data platforms across the full stack. Previously I served as Head of IT at Digital Sacco, where I led a strategic API integration with Onfon Mobile and shipped the Digital Sacco Mini App on the Safaricom M-PESA Super App — extending financial services to millions of subscribers.
I like working at the intersection of engineering and product strategy — where clean code meets real-world impact. When I'm not shipping features, you'll find me flying FPV drones or hacking on my Boomy robotics platform.
