03 / About

Solid engineering.
A practical, personal approach.

Analytical by nature. Pragmatic in delivery.

I’m a computer engineer and data engineer based in Spain. I enjoy building tools that you can understand, use and maintain without unnecessary technical complexity.

I’ve spent more than 4 years building data architectures, APIs and automations for large organisations. I now apply that experience to custom web applications, using AI as a development tool with technical oversight, to help other businesses save time.

I combine logical thinking with creativity. I like listening, understanding the problem and finding a practical solution. Away from the keyboard, I play chess, solve puzzles, keep active and travel to discover other cultures.
