S4MUR41Daemon@system:~/about

$ Junior Full Stack Developer with real hands-on experience. Currently interning as Full Stack Developer at Nervia (Spring Boot + Angular), building investment applications with Helm and CronJob scheduling.

$ Cloud certified: AWS Cloud Practitioner and Azure AZ-900. Cambridge C1 English. Always looking toward the technological horizon and ready to work in international environments.

$ Passionate about game development: currently building a 2D Roguelike in Godot 4 as my final degree project. Code is the tool — games are the ultimate goal.

$ Award winner at The Wave Hackathon 2025 (ECODES) with the Greenstep project: a sustainable mobility app tracking carbon footprint with an eco-token reward system.

$ Outside the keyboard: gym & sports, classic fantasy fiction (Tolkien, Sanderson, Hobb...), video games in all their forms, and any technology worth taking apart.
