Christian Rogobete, a key Stellar SDK contributor known as Soneso, has developed and maintains iOS, Flutter, and PHP SDKs while working on an AssemblyScript Soroban SDK. His work aims to make blockchain development more accessible to developers across multiple programming languages.

The second edition of the Developers on Stellar series profiles Christian Rogobete (Soneso), whose Stellar iOS SDK won first place in the 2018 Stellar Build Challenge. Beyond iOS, Christian maintains Flutter and PHP SDKs and is actively developing an AssemblyScript Soroban SDK to simplify smart contract development. A computer science graduate who worked for major companies like BMW and Siemens, Christian discovered Stellar in 2017 and was impressed by its developer documentation. Driven by a passion for making programming accessible through open-source materials, he contributes significantly to Stellar's SDK ecosystem and hopes to lower barriers for developers building on Soroban.
