Hey there, I'm Arthur 👋

Software Engineer

I love building things that work quietly in the background — pipelines that never miss a beat, systems that recover before anyone notices they stumbled. Based in Kampala, working with teams around the world for over 6 years.

Whether you're here to check out my work, consider me for a role, or just say hello — I'm glad you stopped by.

Things I've built
for fun

GitHub Live

Fantasy Rugby API

I designed and built the backend for Fantasy Rugby, a platform where users assemble virtual teams from real players and compete based on live match performance. It extends the fantasy sports model to a sport largely underserved by existing platforms. Built solo with Flask and PostgreSQL, deployed on Render with SSL-secured connections, and paired with separate mobile and web clients built by collaborators. I own the API design, data modeling, and scoring logic end-to-end.

A RAG chatbot grounded in my actual CV — ask it anything about my experience, and it answers from real content instead of guessing. Try it below.

RemoteRadar

An Airflow pipeline that pulls remote job postings from Remotive, We Work Remotely, and Himalayas, enriches each one with an LLM to extract required skills, seniority, and genuine remote-friendliness, then surfaces the results on a live dashboard. Built to answer a real question I had about my own job search: what does the remote market actually want right now?
