Hi, I'm Fran 👋

Backend Developer · Java · Spring Boot · Hexagonal Architecture

About Me

Backend developer with 4 years of experience building microservices with Java and Spring Boot. I design systems under Hexagonal Architecture, with testing via JUnit, Mockito, and Testcontainers.

I've worked on event-driven systems with Apache Kafka, reactive APIs with Spring WebFlux, and deployments on Kubernetes and AWS (Lambda, S3). Recently completed a specialization in AI and Big Data (2025).

Featured Project · Videogame Library System

A multi-service personal project:

🎮 Backend — Java 25 / Spring Boot 4, Hexagonal Architecture, JWT auth, IGDB API integration
📊 Analytics microservice — Apache Kafka, real-time event consumption
🖥️ Frontend — Angular
🦀 Rust port — backend rewritten in Rust as a language and architecture exploration
