// About Me
BUILDER
by nature,
SHIPPER
by obsession
I'm a software engineer with over 3 years of experience building and shipping full-stack web apps that actually work. I love the challenge of taking a wild idea and making it a reality on the web.
My secret sauce is Effect-TS — I'm a big fan of writing rock-solid, type-safe, reliable code. On the frontend I reach for React and love building systems that feel as good as they perform.
Lately I've also been diving into Swift/SwiftUI and Kotlin for mobile, and even tried building a simple 2D platformer in Godot
