Senior Full-Stack Mobile & Backend Engineer

Senior full-stack engineer capable of owning the entire stack from native iOS to the backend. Recently shipped YTGrab, a free, ad-free YouTube-audio iOS app (SwiftUI + Share Extension) with a FastAPI/yt-dlp backend on Fly.io, built end-to-end in a weekend for $0/mo. Seeking contract/fractional engineering roles ($80–130 CAD/hr, ~$60–95 USD) for 0→1 MVPs, mobile + backend pairings, or projects prioritizing weekly shipping over meetings. Comfortable with both greenfield development and inheriting legacy systems.
