Arine
Work in progress.
Open to interesting problems.
If you're working on hard data, AI, or platform problems, especially in healthcare, insurance, or anywhere a small team is trying to do too much, I'd like to hear about it.

Systems Architect · Data & AI Engineering Leader
Self-taught technologist who's spent the last decade building data and software platforms for healthcare, insurance, and consumer startups. I like the parts of the job where the system, the team, and the business problem all need to move at once.
