First-Class BSc (Hons) Software Engineering graduate based in Madrid.
I build secure, tested REST APIs with Java, Spring Boot, PostgreSQL and Docker, with additional experience in Python, machine learning and IoT.

My projects focus on REST API design, automated testing, application security, CI/CD and the practical integration of AI and IoT systems.

AI-powered REST API for technical incident management
Spring Boot OpenAI GPT-4o-mini PostgreSQL Docker TDD Swagger Spring Security JWT GitHub Actions Render

• AI-powered incident classification by severity and category using OpenAI GPT-4o-mini
• JWT authentication with Spring Security and role-based access control
• Similarity search to find related past incidents
• CI/CD pipeline with GitHub Actions — tests run on every push, auto-deploy to Render
• 56 unit tests with full TDD approach

🚀 Live API: Swagger UI · Health Check

REST API for automated biodiversity data quality analysis.
Java 21 Spring Boot REST API PostgreSQL JUnit 5 WireMock

• Evaluates GBIF occurrence data using 10 extensible quality rules
• Produces weighted scores across geographic, temporal, taxonomic and metadata dimensions
• Clean separation between API, application, domain and infrastructure layers
• 175 automated tests covering unit, web, persistence, HTTP client and end-to-end flows

Secure Spring Boot REST API demonstrating production-oriented backend practices
Spring Boot JWT Auth PostgreSQL Docker Testcontainers Flyway

• JWT authentication with role-based authorization
• Comprehensive integration testing with Testcontainers
• Database migrations with Flyway
• OpenAPI/Swagger documentation
• CI/CD pipeline ready
