About me

I’m an Infrastructure & Data Engineer with a strong mathematical background, holding a double degree in Computer Science and Mathematics from the University of Granada. My professional experience combines data engineering with infrastructure, automation, and software development, including ETL pipelines, big data processing, containerization, and CI/CD.

Over time, I’ve developed a strong focus on Cloud and DevOps, working with technologies such as AWS, Terraform, Docker, and GitHub Actions. I’m particularly interested in automation, infrastructure as code, scalable architectures, and building reliable and reproducible systems.

During my university years, I also had the opportunity to take part in an Erasmus+ exchange at Politechnika Gdańska in Poland, where I deepened my knowledge of cryptography and algorithmics. That international experience broadened my perspective and taught me to adapt to different environments and ways of working.

Projects

Beyond the code

Electronic music & mixing

I'm interested in electronic music and digital sound. I experiment with mixing as a form of technical creativity, using a Pioneer DDJ-FLX4.

SoundCloud

Illustration

I draw manga and caricatures as a creative counterpoint to technical work. Pen and paper remain a great way to disconnect.

Gaming

Gamer in my spare time. I especially enjoy games with solid progression systems and well-crafted narratives.
