What I Do

Mobile Development

I have been developing mobile applications since 2014, specializing in native iOS development, both in UIKit and with SwiftUI.

My journey in developing REST services had its start in 2014 with platforms such as Azure and Firebase, focusing on securitization, sessions, persistence and scalability. Specialized in Vapor as a framework.

Game Development

Beginning of 2016, started developing video games by specializing in native development in iOS with SpriteKit and SceneKit, and cross-platform with Unity.

Software Architectures

I always work with the best development practices, based on Design patterns and the Clean principles: Code, Architecture and SOLID.


Managing and mentoring small international teams of developers became one of my many responsibilities since 2019, implementing agile methodologies and encouraging the use of clean principles together with CI and CD flows.
