Summary

Full-stack software engineer who ships production software end to end. Designed, built, and launched three products solo: two iOS apps live on the App Store and an AI resume SaaS running real Stripe subscription billing, plus two production websites and four cloud migrations, on a foundation of 8 years engineering enterprise infrastructure. Strong across Swift/SwiftUI, TypeScript/Next.js, and cloud (AWS, Azure, Vercel), with the reliability and security instincts that come from senior infrastructure work.
