About
Software engineering and research with limited infrastructure
My work combines implementation and evaluation. After launch, I focus on maintenance, reliability, cost, access, and clear ownership.
Built and maintained production platforms across legal, education, media, recruitment, and internal operations.
Worked with teams in the Democratic Republic of the Congo and Europe, often with limited infrastructure or operating capacity.
Researching applied computing where infrastructure, cost, data quality, and access shape technical decisions.
