👋 Hi, I'm Diogo Passos!

I'm a Java Full-Stack Developer passionate about building clean, maintainable and user-focused software. I enjoy turning ideas into reliable software through clean code, thoughtful design and continuous learning.

After more than a decade leading a music school and performing internationally, I transitioned into software development through an intensive Java Fullstack Development programme. Today I enjoy building robust backend systems, intuitive frontends and applications that solve real-world problems.

💻 What I Enjoy Building

  • Backend applications with Java and Jakarta EE
  • Full-stack web applications with React
  • RESTful APIs and database-driven systems
  • Real-time applications with WebSockets
  • Clean architecture, maintainable code and automated testing
  • AI-assisted software development

🚧 Currently Working On

  • Developing a public-facing website for a music school with a strong focus on accessibility, responsive design and user experience.
  • Expanding my knowledge of software architecture, testing and modern development practices.
