Who I am

DM
Don Marckheil Desmond
Full-Stack & AI Engineer · UMass Amherst

I'm a Computer Science, Data Science & Statistics student at UMass Amherst, graduating in 2028. I focus on building intelligent systems end to end — from the model layer to the product layer. I care about things that ship and scale.

I have shipped production AI systems at AbbVie serving 50,000+ employees, built RAG pipelines that got adopted post-hackathon, and deployed CV systems hitting 92% precision in real time. The work is always production-first.

Outside of work I'm interested in fintech and keep close tabs on where AI infrastructure is heading.
