Portrait of Didin Fachrudin

About

I'm Didin, a product engineer from Surabaya, Indonesia. I like owning a product end to end: deciding what to build, designing it, writing the code and shipping it.

I've built 11 apps of my own, 9 of them for macOS, like Spika, Postka and Klira. Client work runs through my studio, Dayalabs.

If you need an app built, here's how I work.
