Samuel Sierra

I love technology and mobile devices! I’m a software engineer specialized in iOS and iPadOS development, with 7+ years of experience.

Samuel is a software and computer science engineer with a strong passion for mobile platforms and over eight years of experience in iOS development. He specializes in using Apple technologies, including iOS SDKs and APIs, the Xcode IDE, and web systems such as App Store Connect and the Apple Developer Member Center—effectively working across most of Apple’s mobile ecosystem, encompassing software, hardware, and services.

While Samuel primarily writes code in Swift, many of his past projects have been developed in Objective-C. He has successfully led mobile projects built from the ground up, which are now used by millions of users. His work includes integrating payment systems into iOS applications and developing reusable Objective-C frameworks that simplify access to complex network systems for other developers.
