ABOUT ALEX

My professional journey commenced in 2012, and my exploration into Domain-Driven Design began in 2014. This was a pivotal moment that significantly influenced my approach to subsequent projects. As a Software Engineer, I am deeply passionate about learning and advocating for practices such as Domain-Driven Design, Test-Driven Development (TDD), and Extreme Programming (XP) Practices, among others. Additionally, I take great pleasure in sharing knowledge and experiences with colleagues and peers through workshops, pair programming sessions, and enriching conversations.
