At ATB Applications LLC, I’m the Lead Software Engineer on ShaftFitters, a golf shaft recommendation platform built from golfers’ own swing data. I built its iOS and Android apps, backend, and web app, and the product is live on the U.S. App Store.

At Homiee, I architected core systems for a real estate platform, including property search with sub-100ms latency and agent dashboards. I also engineered an AI chat system and a computer-vision pipeline for property videos, cutting detection payloads from 200MB+ to 2–4MB.

I also build products independently, including Tutorly-AF Academy, with live classes, an AI tutor, and adaptive video streaming, and Paycore, a payment platform designed to stay correct under failure. My work spans mobile, web, backend, systems engineering, and AI, using TypeScript, Go, Python, and Rust.
