I have been building production-grade full-stack and AI-powered systems for 7+ years, shipping everything from real-time IoT dashboards and multi-tenant SaaS platforms to LLM-powered multi-agent workflows using LangGraph.js and Anthropic Claude. I have achieved 99.9% uptime across mission-critical platforms, reduced API latency by 30-45%, and delivered 0-to-1 products serving 50+ institutional clients across fintech, civic tech, and digital health sectors. I am looking for senior engineering roles at mission-driven organizations building infrastructure that governments, NGOs, and underserved communities genuinely depend on. What sets me apart is the combination of deep full-stack engineering craft, hands-on AI integration experience, and the ability to operate as a principal-level engineer who sets technical vision, raises team standards, and ships autonomously in fully remote, cross-cultural environments - all from Nairobi, with strong overlap across Africa and European timezones.
