I am a developer driven by solving complex problems and a commitment to continuous learning. My portfolio demonstrates versatility across the stack: from building robust architectural systems in Java to solving high-performance algorithmic challenges in C++ and creating impactful data visualizations.

• 🎓 Focus: Software Engineering, Data Structures, and Complexity Analysis.
• 🛠️ Specialties: Clean Architecture, Algorithm Optimization ($O(n \log n)$), and efficient data handling.
• 💡 Philosophy: "Clean code and efficient logic are the foundation of any great solution."

A comprehensive collection of 100+ optimized solutions developed for the UPC-FIB curriculum.

• Advanced Logic: Implementation of Graph Theory (Dijkstra, BFS/DFS), Dynamic Programming, and Backtracking.
• Performance: Focus on time/space complexity analysis and C++ STL efficiency.
• Documentation: Structured portfolio with automated index generation and detailed categorization.

Professional implementation of a KenKen generator and solver in Java.

• Backtracking: Optimized algorithm for solving complex board constraints.
• Clean Architecture: Strict separation between Presentation, Domain, and Persistence layers.
• GUI: Intuitive user interface developed using Java Swing.

Data analysis and visualization project for potentially habitable exoplanet candidates.

• Data Analysis: Processing NASA datasets using Python.
• Visualization: Interactive timeline using D3.js to explore the Earth Similarity Index (ESI).

Full-stack monorepo for a Barcelona culture and leisure app: points of interest, itineraries, events, passport/gamification, and user features.

• Backend: Django REST Framework, PostgreSQL, JWT authentication, OpenAPI (Swagger), Firebase Admin for notifications.
• Mobile: Android app with Kotlin, Jetpack Compose, and integrations with maps, mobility APIs, and Firebase (Auth, FCM).
• Structure: Single repository with clear backend/ and frontend/ separation for API and client.

Full-stack Hacker News–style platform (ASW — web applications and services): news feeds, submissions, comments, threads, voting, and user profiles with API-key authentication.

• Backend: Django, Django REST Framework, OpenAPI documentation (Swagger / ReDoc), django-allauth (Google OAuth), optional AWS S3 for media, SQLite locally.
• Frontend: React 18, Vite, React Router, axios; environment-based API URL and profile keys.
• Structure: Monorepo with backend/ and frontend/, secrets via .env / .env.local (no credentials in the repo).
