Jairo García Antolín

What i do

Software developer based in Málaga-Spain, specializing in building robust and scalable systems.

I'm currently working towards expanding my technical horizon into Data Engineering, Artificial Intelligence & Backend solutions.

I am passionate about creating systems that not only function flawlessly but also process, validate, and leverage data intelligently.

Who ami

I'm just a guy who loves technology, videogames and discovering things.

I'm addicted to the feeling of keep onlearning new things:cities

I'm certain that's how we keep on growing and rediscovering ourselves.

My favourite childhood game was Elsword, a side scrolling 2.5D action game where i competed against many other skilled players around the world.I won the biggest European tournament of Elsword's history back in 2016, i traveled to Cologne (Germany) where i would be crowned as the European champion at the Gamescom after a well-heated long competition.

I believe that the same kind of discipline i have to win that trophy is also required to optimize, build and come up with solutions that can actually help people and improve systems.
