About
From field operations to production systems.
I'm Emmanuel W. Wachira, a full-stack and AI engineer in Nairobi. I spent six years as a service engineer at KOKO Networks, keeping smart energy infrastructure running for thousands of customers across the city. That is where I learned that software only matters when it works in the field.
Since training at Moringa School I've shipped two full-scale platforms: LogiFlow, a multi-tenant logistics SaaS on Django and Next.js, and FlixVideo, an AI-powered streaming and discovery platform on Node.js and Next.js. Both run with CI/CD, Prometheus and Grafana monitoring, and Stripe, M-Pesa and crypto payments.
Most recently I built The Pour Is Right: a fine-tuned open-source model, RAG and an ensemble that price wine, with LangGraph agents that hunt for real deals. I'm open to full-stack, DevOps and AI engineering roles.
