I am a hands-on senior iOS Developer with over 20 years commercial programming experience and over 4 years experience developing commercial iPhone/iPad applications.
Although I am very focused on iOS development, I do have significant senior management experience which is often useful in project planning, execution, team mentoring and in client-facing situations.
I care passionately about usability and maintainability of the software I create. I find maintainability brings a focus on testability, automation, separation of concerns, evolving systems sympathetically with their original intent, using appropriate technologies, making illegal states unrepresentable and removing barriers to iteration speed. My interest in maintainability is leading me to be increasingly interested in strongly-typed functional languages; such as Haskell and Swift.
