¡Hi! 👋🏼 I'm Miguel Segura, FullStack Developer

I'm a Web Developer who loves to get involve in creative and challenging projects, I love to learn new things and be very agile. I also take the initiative to resolve my problems and take the oportunities to the next level.

Likewise, I think that I reflect a lot in my work the values and what I have learned as a Hiker, Dancer, and Bodybuilder.
