👋 Hi, I'm Marco Antonio

Full Stack Developer with experience in enterprise systems, working across backend and frontend.

I've been building and maintaining web systems since 2022 — from legacy Java EE systems to modern REST APIs and Vue.js frontends. Currently working as a Java Developer at Holos Consult, focused on system evolution, SQL optimization, and clean architecture.

My main stack includes Java, Spring Boot, Vue.js, PostgreSQL and SQL Server, with hands-on experience applying SOLID principles, Design Patterns and MVC in production environments. Always learning — currently diving deeper into AWS, Docker and Kotlin.

🚀 About me

  • 💻 Full Stack Developer — Java, Spring Boot, Angular, Vue.js
