About Me

I’m a developer passionate about building scalable, data-driven solutions, based in Spain.

My journey began in web development, playing around with React and front-end technologies, but my curiosity pulled me deeper into the world of Big Data and Machine Learning.

Currently focused on designing data pipelines, building AI-powered systems, and architecting lakehouse solutions to make sense of massive amounts of data. I love solving scalability challenges, optimizing performance, and fine-tuning cloud-native architectures for speed and reliability.

When I'm not wrangling data, I'm usually lifting at the gym, buried in a book, exploring new places, or on the hunt for my next favorite meal.
