About.

I'm a Lead Engineer with a solid background in backend engineering and core platform developments based in Madrid, Spain.

Since 2015, I've focused on building the backbone of successful products. I advocate for scalable architecture, not just for performance, but for team velocity and long-term maintainability. My expertise is converting business vision into a technical reality, strongly emphasizing good practices and a product-first mindset. When I'm not coding, you'll find me exploring new technologies, enjoying outdoor activities, or perfecting my coffee brewing techniques.
