I’m Dan Ilies. I build mobile apps, websites and backends, with mobile development at the heart of my work.

Selected work

From skin and color scanning to the points I play on court.

FitSkin

Skin & color scanning · Lead mobile developer

From scanning algorithms to the apps people use. I lead mobile development at FitSkin, the company behind Sephora’s and No7’s skin-scanning apps. My work spans the scanning algorithms, core SDK and partner apps.

MyTennisGame

Apple Watch · Personal project

Built for the matches I actually play. I built the Apple Watch app to track points and turn them into match statistics. I use it in my own matches; launching soon.

A little about me

I like being close to the work: writing the code, working through the difficult parts, and talking directly with the people using and building the product. I’m also open to consulting when a conversation is what’s needed.
