James Wegner
Hi, I’m James, a senior software engineer based in New York City focused on AI-native mobile product development.
I’m interested in the intersection of technology and the humanities, which led me to study computer science and anthropology at the University of Illinois Urbana-Champaign.
I’ve worked on a wide range of products and experiences, including Facebook Events, telehealth and mental health care for K–12 students at Hazel Health, visual search with Google Lens, and shopper checkout flows at Instacart.
I’m currently looking for a collaborative team building thoughtful, user-centered AI-powered products across web and mobile.

Integrates static GTFS MTA transit feed data and live GTFS feeds for real-time trip updates, backed by a full-stack API built with Next.js, Vercel, and Supabase.
