Hi there 👋, I'm Duong Le
I'm a software engineer with over six years of experience building web applications, from early-stage products to systems running in production. My work spans the stack — from interfaces to the logic and infrastructure behind them
This site is where I document that work: engineering notes, projects, and the occasional deep dive into a problem worth writing about.
