🧠 Software Engineer | Tech Founder | Building Intelligent Systems
I’ve been passionate about technology since I was 14 years old, when I started building videogames in ActionScript (Flash).
That early curiosity evolved into a long-term commitment to software engineering and systems design.
I studied Computer Science at the University of Barcelona (2014–2018) and have since worked as a full-stack software engineer at companies such as NTT Data, Allianz Technology, and currently Kids&Us.
Alongside my professional career, I build AI-driven systems and SaaS products — combining strong backend engineering with modern AI orchestration frameworks.
I enjoy experimenting with emerging technologies, designing scalable architectures, and applying solid engineering principles.
I’ve completed multiple trainings in Clean Code, Clean Architecture, Spring Boot, AWS Cloud Architecture, and Generative AI.
I’m also starting my journey as a tech content creator, sharing insights and experiences on my YouTube channel:
