About

Front-end at heart, curious by nature

I'm a Computer Engineer from Universitat Pompeu Fabra and front-end is my foundation. Over 2.5 years at NTT DATA, first as an intern and then as a junior developer, I worked on an internal management platform for the public healthcare sector, live in 3 hospitals in Catalonia: mostly with Angular and TypeScript, but also with Java / Spring Boot REST APIs, PostgreSQL and the integration of PDAs with barcode, RFID and NFC readers.

That curiosity about what happens behind the interface is pushing me towards full stack. I now build websites for clients and work with AI-assisted development every day: Claude Code, agents and custom skills that help me build, review and automate. To me, AI is one more tool of the trade: it speeds things up, but the judgement and the care for doing things right are still mine.

Outside work I'm Catcrac, my gaming nickname. And it's not just a hobby: my final degree project was about cooperation in multiplayer video games and I'd love to make games for a living. I'm looking for a product team where I can keep growing steadily towards a mid-level role, learn from great people and do things right.

My journey so far

  1. WorkMar 2024 – Oct 2026

    Front-End Developer

    NTT DATA Europe & Latam

    Junior Developer (Sep 2025 – Oct 2026), hired after my internship (Mar 2024 – Jun 2025).

    Internal management platform for the public healthcare sector, live in 3 hospitals in Catalonia.

    • Developed 30+ screens and dynamic forms in Angular 14+ / TypeScript and Angular Material, within a team of ~20 people.
    • Built the PDA integration from the ground up: connected the devices' library for barcode, RFID and NFC (patient wristbands) reading and writing to the Android app (Java, Android Studio) and the Angular front end, and managed the resulting data flow.
    • Designed and implemented 80+ master data tables (schema and data scripts) in PostgreSQL within a few weeks, using H2 for local development.
    • Implemented REST endpoints in Java / Spring Boot and fixed bugs across front end and back end.
    • Used AI-assisted development tools to speed up delivery, working in iterative development blocks with Jira, Git and GitLab.
  2. Education2019 – 2025

    BSc in Computer Engineering

    Universitat Pompeu Fabra (UPF), Barcelona

    • Final degree project: "Analysis of mechanics in multiplayer video games and their impact on the type of cooperation" (grade 9/10), with 3 online multiplayer prototypes in Unity, C# and Unity Netcode.

Projects

Things I've built

A mix of client work, university projects and my own tools, almost always with AI as a teammate.

  • Personal project (pro bono) · Oct 2026 – present

    Asbestos certificate requests

    Website that collects asbestos certificate requests in Catalonia and emails them to a small business. I defined the requirements directly with the client. In Spanish and Catalan, with a private dashboard to manage them. Built with AI-assisted development (Claude Code).

    Final degree project · UPF · Grade 9/10

    Final degree project: cooperation mechanics in multiplayer games

    I analysed 44 co-op video games and proposed 3 types of cooperation (communication, planning and coordination) and 21 mechanics that encourage them. I validated them with 3 online 2-player prototypes (waves of enemies, environmental puzzles and ability synergy) and a study with 20 participants: the mechanics directly shape the type of cooperation that emerges.
