About me

I'm a Higher Technician in Multiplatform Application Development (DAM) with proven experience in corporate software development, currently specializing in Cybersecurity. I've participated in high-visibility projects such as the Mobile World Congress and in critical healthcare systems.

My approach is distinctive: I bring a developer's perspective to the security world, allowing me to understand and protect infrastructure, applications, and cloud environments comprehensively. I'll soon be starting a Computer Engineering degree at UOC.

I'm looking for my first opportunity in cybersecurity, particularly in roles where I can combine my technical development background with the offensive and defensive skills I'm building.
