Not sure where to start?
Tell me about your idea and we’ll figure out the right first step together.
Structure and intuition, in balance.
Code is my structure: logic, systems, rigour. Piano is my intuition: feel, taste, space. They pull in opposite directions, and good products need both.
Structure
- End-to-end ownership
- UI, UX and development by the same person, through release and maintenance. No hand-offs, nothing lost in between.
- Clean, efficient code
- Native code that is clean, elegant and efficient, built with Apple’s own frameworks so your app is fast and easy to evolve.
Intuition
- Product thinking
- I’ve designed, built and published my own apps, so I think about the whole product (users, purchases, updates), not just the feature list.
- Interfaces that feel right
- Interfaces and experiences designed around your users, with attention to the details people notice without knowing why.
