At Globant, I develop financial applications covering FI, agreements, customers, and cards. My work includes Angular 20+ Signals front-end development, feature planning, and codebase maintenance.

At GFT Technologies, I developed debit back-office features and maintained Open Finance for Santander Bank, using Angular with GraphQL and Apollo. I also reviewed code and provided technical support to junior developers.
