Backend muscle.
AI intelligence.
Real products.

I'm emmatt, a Backend & AI Engineer who builds the infrastructure underneath intelligent products. From high-performance REST APIs and data pipelines, to RAG systems, LLM integrations, and AI-powered applications that actually work in production, not just in demos.

I sit at the intersection of solid engineering and modern AI. I care about reliability, latency, and making sure the "AI layer" doesn't collapse the moment real users show up. Based in Accra — building things that work anywhere.
