About me

From data to product.

At LeanMind since 2020, working on data pipelines, web applications and backend systems. What connects those projects is how I work: understand the context, test decisions and collaborate with the team.

Outside the project, I write and share what I’m learning.

“On the different occasions when I have had the opportunity to work with Airán, it has been a real privilege, as he is a great professional and teammate. He has demonstrated extensive knowledge of both back-end and front-end development, implementing intelligent solutions using methodologies such as TDD or XP. His experience with code gives you tremendous confidence and peace of mind day to day, and he integrates perfectly into the team. I would genuinely love to work with Airán again on another project and continue learning from all the knowledge I know he has to offer.”
