About Me

I have a wealth of experience working with clients from all around the world. The work I provide is of the highest quality, fully responsive, and tested in a wide range of devices. I take great care to ensure each project is well-architected, well-documented and easily maintainable so you can enhance an app as your company grows. I maintain a high code quality standard. Writing code that is documented and easy to read means it can be maintained and scaled in the future and allows co-workers to quickly work with it.

I've been developing natively in Swift & SwiftUI for almost 10 years. I believe that native apps give the best results and have the least problems when it comes to adopting new iOS features, iOS versions or when new devices are released. I also have direct experience with Apple's policies, device capabilities and account management procedures alongside with a good understanding of what it takes to maintain apps over the long term.
