    1st Place in 'Coding Challenges: Round 1 - Christmas Edition' by CaixaBank Tech


    On January 9th, 2025, I participated in the 'Coding Challenges: Round 1 - Christmas Edition' organized by CaixaBank Tech and achieved 1st place in the Backend - Java category.
    In this challenge, I had to implement a robust backend system for a financial application using Java. The tasks involved creating a secure user authentication system, account management features, transaction logic (including deposits, withdrawals, and transfers), Docker configuration, and an investment module with periodic interest calculations.
    This experience pushed my backend development skills further, especially around designing APIs with proper security, using JWT, Docker, and implementing real-world banking logic. I’m proud of this achievement and excited to keep growing as a developer.

        3rd Place in the National AWS JAM


        Yesterday, May 29, my teammate Guillermo Bernal and I participated in the national AWS JAM Spain competition. This event brought together various teams from all over Spain who had qualified in December. In total, 24 teams participated, each composed of 3 or 4 members, except for us, as we were only two.


        In the competition, we initially finished in 2nd place, which eventually became 3rd due to a time adjustment that was communicated to us. Despite not winning, we worked as a team and achieved an excellent position, being the team with the fewest members. It was an honor to participate, enhancing our knowledge of AWS and giving our best effort.
