How I work
I start with the user tension, then shape the smallest useful thing worth shipping.
From interface to infrastructure, I make pragmatic technical choices that hold up.
I automate the repetitive parts and improve the tools so the next release gets easier.

Hold to pour, release to pause. With a keyboard, Enter or Space starts and pauses. A playful take on latte art.

I'm Ed, a software engineer in Taiwan. When I'm not building, I'm usually chasing snow, getting lost in a new neighborhood, or enjoying a latte with a little art on top. Lately, I've been making room for pickleball, too.
