Professional Profile
I build mission-critical products at the intersection of AI, healthcare, open source, and infrastructure. Over 25+ years I have moved from enterprise infrastructure and compliance work into product leadership, company building, and hands-on engineering.
Recent work includes building patient and AI workflow systems at Legion Health, founding Unproprietary Corporation, and creating UnInbox, an open-source email platform that reached the top 0.03% of GitHub repositories and became Product Hunt's #1 Product of the Day.
My work is shaped by zero-to-one execution. I have started multiple companies, built and exited one, led teams through hypergrowth at ClickUp, judged hackathons, and built communities and OSS projects used by founders, developers, and healthtech operators.
