Hi, I'm
Eugenio Estrada
CTO at Difoosion & Specialist in Software Engineering and AI
Passionate about technology, software development, and the transformative impact of Artificial Intelligence. With over 15 years of experience leading the development of large-scale digital media platforms and enterprise CMS solutions, my current focus lies on the practical application of AI in Software Engineering to automate workflows, elevate code quality, and accelerate the development lifecycle. If you want to know how I started, you can read it in my origin.

Life Beyond Code
Sports & Health
To balance my time in front of screens, I enjoy challenging myself physically. I regularly train in strength, running, and swimming. A recent milestone I'm proud of was crossing the finish line of my first half marathon in March 2026.
Pop Culture & Leisure
From books, consoles, and the screen. I am fascinated by sci-fi and fantasy storytelling, whether in video games or epic sagas. I follow the Marvel universe closely, and if you ask about TV series, I will always defend that LOST reshaped television storytelling forever.
