Hi, I'm Hoang.

Software engineer in Geneva, working in TypeScript, Go and C#. Web platforms by day, an open source chart library by night.

Chasing @paulirish's dream: make the WWW great. Off the keyboard, you'll find me doing calisthenics 🤸‍♀️.

Off the keyboard

Saxophone

Learning on a Yamaha YDS-120 electronic saxophone. I got impatient with not knowing whether I was actually improving, so I built a practice tool that listens over MIDI or microphone and keeps score.

Calisthenics

Bodyweight training, no gym required. The long game: a clean planche.

Tennis

A different kind of interval training. The backhand is a work in progress.

Cycling

Two wheels, long roads, no notifications.
