I'm a software engineer specialized in iOS development and recognized for my contributions to open-source projects, including the creation of CryptoSwift, a Swift library for cryptographic operations, or ObjectivePGP, an iOS/macOS open-source library for secure OpenPGP encryption and digital signature, or Online Swift Playground, and SwiftStudio. Recently, I did a deep dive into Text Kit with the STTextView component, which is a reusable and extensible text view built from scratch. Another tool is VMDesktop which is a Linux Virtual Machine launcher for macOS. My passion for programming and software design drives me to continuously explore new technologies and contribute to the advancement of the software engineering field. My work in the tech community has involved not only developing innovative tools but also sharing knowledge through speaking engagements at technology conferences and active participation in software development forums.
