Software Engineer & Full Stack Developer

Madrid, Spain

Final-year Software Engineering student with a Full Stack profile. I combine a strong technical foundation with experience in the design and architecture of modern software solutions.

At Génexys, I contribute to technical decision-making and the development of microservices-based architectures using Python and AWS. My technical approach builds on my previous experience at Telefónica, where I worked within professional development workflows, collaborating on the development of scalable projects and the optimization of web performance.

I currently apply these same engineering principles in my Final Degree Project (TripFlow), where I design a microservices-based PWA using Spring Boot with generative AI integration.
