Engineer. Builder.
Impact-driven.

I'm Osei Japhet Acquah — a CS & Data Science student at Pomona College, class of May 2028. I build across the full stack and into AI — wherever the most interesting problems live.

From edge AI systems processing 1K+ events per second to hackathon-winning accessibility apps, I care about the craft: clean code, real tests, products people actually use. And through The Ckedon Foundation, I mentor students in Ghana — opening doors the way they were opened for me.
