I'm a long-term Senior iOS Developer, having been professionally developing full-time for the platform since 2010. I invest a great deal of time in attending conferences, giving talks on emerging ideas, contributing to open source projects, and developing Tacks, my own app.

I'd love to screen-share and discuss your project, maybe walk through some code or do some pair-programming so you can find out if I'm a good fit for your team - just shoot me an email.

I'm based in Haarlem, near Amsterdam.

How can I get in touch?

I’m @id on Twitter, you can email me or iMessage me at contact@iandundas.com, and on Skype I'm ian-dundas.

What is your experience level?

Seasoned. I’ve shipped at least 20 apps of many kinds and have thus become intimate with a wide range of iOS design patterns and frameworks.

More generally I've been freelancing since 2009 and have worked with many different languages and setups, so I count myself as a full-stack developer.

What technologies do you use?

I now write Swift fulltime (💖) but retain a deep understanding of Obj-C. Any backend stuff is generally in Ruby or JS.

I'm super into Functional Reactive Programming (ReactiveKit, ReactiveCococa, Rx), and it's uses combined with Swift are continuing to blow my mind every day.

Of course I use AutoLayout, the MVVM pattern (actually, MVVM-C of late), Storyboards when appropriate, etc.

Do you write tests?

Yes of course! 😎 Primarily I test my ViewModels with Quick, but I've been experimenting with adopting automated UI testing (with fastlane) for my Tacks project.

Where are you located?

I live in Haarlem, North Holland.

Are you willing to travel?

Yes definitely! I'll come to you.

Will you use cross-platform technologies? (PhoneGap, Appcelerator etc)

I code natively in Swift or Objective-C (I've much more experience there)

Do you write Android apps?

I'm afraid not - as a one-man shop I've found it better to concentrate on one platform than try to be a jack-of-all-trades. (the iOS platform changes fast enough already!)

Do you do visual design?

No, but I know a handful of great designers who could help with that.

Will you work for equity?

Almost certainly not, unfortunately. (Unless you're Apple.)


It was a honor to work with you. I really liked the way we approached problems and solved them. You are a real senior in what you do.
