James Wegner
Hi, I'm James. I'm a software engineer based in New York City with a background in iOS development and consumer product engineering. Over my 10+ year career, I've built mobile experiences at Google, Meta, and startups, most recently working as a Senior iOS Engineer on Google Lens.
I'm currently on a career sabbatical focused on building side projects and deepening my expertise in AI, with a particular interest in mobile AI, on-device models, and retrieval-augmented systems. With an educational background in computer science and anthropology, I'm especially interested in the intersection of technology, the humanities, and everyday life.
Outside of work, I spend my time learning music production, taking photos around the world, and staying active through running, surfing, and hip-hop dance.

Projects
NYC Local
VisitFull-stack NYC event discovery platform that aggregates events from multiple sources and uses AI to improve search and categorization. Designed a multi-stage ingestion pipeline to scrape, normalize, deduplicate, and enrich event data from sources like Luma, Partiful, and Eventbrite. Implemented LLM-based tagging, semantic embeddings, and hybrid keyword plus vector search using pgvector to create a more intelligent discovery experience.
MTA Times
A native iOS application designed to provide real-time subway departure times in New York City. Built entirely with SwiftUI and leveraging iOS's geolocation capabilities, the app offers a seamless experience where users can simply open the app to view an automatically generated timetable for the nearest subway stop, along with a map for selecting other nearby stops. 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.
My Bus Helper: MTD
App StoreAn iOS application built with Swift and Objective-C that serves the Champaign-Urbana transit community. Using MapKit, CoreLocation, and the local transit API, the app provides real-time bus departure times, route information, and stop locations. Currently maintains 4,100 monthly active users with a 4.6-star average rating with over 900 reviews.

Personal goal pursuit — Career break
2024 – Present
- On a self-directed career sabbatical focused on technical growth, side projects, and creative explorations. During this time, I've been deepening my expertise in AI and expanding beyond my iOS background into full-stack product development, with a particular interest in mobile AI, on-device models, and retrieval-augmented systems.
- Participated in the Recurse Center, a self-directed intensive retreat for programmers, where I learned full-stack web development using Next.js, TypeScript, and React. I built an API for accessing real-time NYC subway departure times and a native iOS app using SwiftUI, Combine, Swift Concurrency to interface with it.
- Built NYC Local, a full-stack event discovery product that aggregates NYC events from multiple sources and uses AI to improve search and categorization. The platform combines LLM-based tagging, semantic embeddings, and keyword search, giving me hands-on experience with retrieval-augmented patterns and end-to-end product development.
- Creative pursuits: Second City improv classes, 343 Labs Ableton music production lessons, and hip hop dance workshops at Broadway Dance Center.
