  • quote icon Michael Mathieu

    I had the pleasure of working closely with Tomás for 2.5 years on a variety of projects, including the development of a complex Android native app that integrated an NDK-based machine learning model. Though he was new to native Android development at the time he is always up for a challenge. Throughout our time working together, he demonstrated exceptional technical expertise, particularly as a mobile Flutter developer, where his contributions elevated our capabilities in every area of the mobile stack. One of his standout accomplishments was designing and implementing a robust CI/CD pipeline that streamlined our development process and improved the overall efficiency of our team.
