I'm Tuan, a software engineer from Vietnam. For over a decade I've built tools that remove friction from everyday operations — order systems for busy counters, scheduling for schools and clinics, and automation that quietly deletes hours of manual work. I care about software that is simple to run, easy to understand and useful from day one.
