✦Software Developer · Spain

I build software
for real problems.

I work between backend and business — from SAP and .NET to modern interfaces with React and Next.js. I cover the full lifecycle of a product.

✦About

3 years building software that's used every day.

I'm a software developer based in Spain. My work sits between code and business: understanding real processes and turning them into tools that work in production.

Since 2023 I've been working at Litalsa, developing applications in Blazor and C#, and rolling out solutions on SAP with ABAP. In parallel, I build projects with Next.js and React, where the interface matters as much as the logic.

What interests me is the less visible side: architecture, integration between systems, and the detail in the interface. That's where a product actually starts to work.
