Full-Stack Engineer & Tech Lead
📍 Nairobi, Kenya · 📧 okumu.oriaro@gmail.com · 🌍 Remote-friendly · Open to freelance projects
I build fast, scalable web systems for growing businesses — from frontend to cloud deployment.
For the past 4+ years at Yellow Pages Group, I've led a 15-person team across Kenya, Cape Verde, and Mozambique — delivering full-stack platforms, AI-powered automations, and infrastructure that runs reliably at scale. I work at the intersection of engineering and business: I don't just write code, I understand what the system needs to do for the people using it.
Currently available for freelance projects and fractional technical leadership engagements.
