I’m Dan Ilies, a mobile developer who also builds the web and backend behind the app. I work directly with founders and teams, from prototype to the App Store and beyond.

Lead mobile developer at FitSkin, whose scanning technology is in Sephora stores around the world and used by No7 UK and Olaplex. Building iOS and Android apps since 2015.

My Tennis Game

iPhone & Apple Watch · Personal project

My Tennis Game on iPhone and Apple Watch: an example match’s score and momentum graph on the phone, and live scoring with a button for each player on the Watch

Built for the matches I actually play. I built the Apple Watch app to track points and the iPhone app that turns them into match statistics. I use it in my own matches, and it’s now on the App Store.

How I work

Start at any stage.

  1. Idea

    We shape your idea, decide what to build first and agree on a clear plan.

    Start with an idea

  2. Prototype

    I build a focused proof of concept to test the idea. It can be ready in 1–2 weeks, depending on scope.

    Example: an AI recipe app prototype

    Test an idea first

  3. Build & launch

    I build and launch your app, from scratch or from your prototype, with the web and backend behind it where needed.

    Ready to build

  4. Long-term growth

    I maintain your app, add features and adapt it as your needs change.

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.

Let’s talk

Have something you’d like to build? I’m most interested in projects I can get hands-on with, from mobile apps to the web and backend behind them.

What happens next

  1. You tell me what you’re working on.
  2. I reply by email with a few questions or first thoughts.
  3. If it’s a fit, we set up a call at a time that suits us both.
What’s on your mind?

Tell me what you’re building, where you are in the process, and what you need help with.
