Rails is my weapon of choice — API-first apps, Hotwire interactivity, background jobs, payments, and complex business logic? All handled. I build with intention, scalability, and UX in mind. Beyond code, I’ve co-founded multiple products, run lean experiments, managed integrations with payment gateways (M-Pesa, Stripe, Paystack, Circle), and built systems used by thousands in Kenya and beyond. I speak startup.

I didn’t start out planning to be a developer—but solving problems though applied technology pulled me in. What began with scripting solutions for tedious workflows turned into building full-scale platforms used by thousands. Today, I’m a full-stack developer and technical founder with a deep understanding of both code and the business logic behind it. I have worked across both public and private sectors, and in industries ranging from Logistics and Aviation, to Retail and Education. My early career experience as a solutions architect reinforced my customer and user concentric approach. What sets me apart isn’t just the code I write—it's my ability to understand what users actually need and deliver scalable, elegant solutions that exceed expectations.

Also experienced in mentoring devs, improving performance, and navigating compliance (HIPAA, PCI, ISO27001). Currently open for ~10 hrs/week of contract work—hands-on coding, tech guidance, or both.
