About Me

Engineer. Builder.
Problem Solver.

10+ years shipping production systems across Africa, Europe, and the US.

I hold a First Class Honours degree in Computer Engineering from Ghana Communication Technology University, where I graduated as Top Student. My career has taken me across FinTech (pan-African insurance at 20M+ scale), coaching SaaS, workforce management, and AI infrastructure.

Today I specialise in two areas: scalable distributed systems (Java/Spring, Python/FastAPI, Kubernetes on AWS/GCP) and AI-powered product engineering (LangGraph, LangChain, OpenAI GPT-4o, production MCP servers). I work remote-first and speak English and French fluently.

Scale by Design

I've built and shipped features on systems serving 20M+ users across 5 countries — from development to deployment, with reliability and scale in mind.

AI-First Engineering

LangGraph multi-agent orchestration, GPT-4o integration, and production MCP servers — not demos, shipped products.

Lead & Deliver

I own features end-to-end: architecture, implementation, deployment, and the team processes that keep quality high.
