Hey, I'm
Erfan Gholami
Android Engineer · Turin, Italy
I've been building Android apps for over seven years — the kind that work in the middle of nowhere, show you where you are on a map, and don't drain your battery doing it.
Most of that time I've been the sole Android engineer on small teams, which means I've had to care about everything: architecture, performance, testing, shipping. I like it that way.
Lately I've been deep in open-source work — building tools that give people real ownership of their data, funded by NLnet and published for anyone to use.

I'm open to freelance projects, senior roles, and open-source collaborations — especially around location, mapping, or anything that gives users more control over their own data.
