My name is Christian (also known as Soneso in the Stellar Community) and I am the main developer and maintainer of the iOS Stellar SDK. I have a master's degree in computer science and a master's degree in logistics and have been working in the IT field since the mid-1990s as a developer, software architect, project manager, and in other roles.

I began contributing to the Stellar network in 2017, specializing primarily in the development and maintenance of Stellar SDKs. The first Stellar SDK I developed was the iOS Stellar SDK, which won the Stellar Build Challenge in 2018 and has since been expanded and maintained by me with the help of the SDF Infrastructure Grant. Other SDKs I have developed include the Flutter Stellar SDK, the PHP Stellar SDK, and the AssemblyScript Soroban SDK.

The iOS Stellar SDK also has many contributions from other developers, which can be viewed here. I currently work full-time on my Stellar SDK projects. If my capacity is insufficient during peak periods, I have an experienced contractor whom I can hire to assist me with development.

If you want to learn more about me, you can find a nice article about me by Stellar here.
