// summary

Flutter engineer, 5+ years in production. Shipped cross-platform apps across health, EV charging, and media — from writing a native video-streaming plugin at a startup to leading architecture decisions at a B2B scale-up. Strong opinions on testing and architecture; I care about what happens to code after it ships.
