🏛️ Marcio Moreira | Architect ➔ Developer 🛡️

"Architecture matters. Structure brings balance to code."

I am a developer with a background in Architecture and a passion for building—and securing—complex digital structures. I’ve traded physical blueprints for technical ones, moving from designing buildings to managing mission-critical enterprise logic and exploring the world of cybersecurity.

🚀 Professional Focus

  • Core Systems & Data: Currently managing mission-critical logic as a COBOL and PL/SQL Developer, focusing on enterprise reliability and Oracle environments.
  • Full Stack Foundations: Leveraging the Java Spring ecosystem and JavaScript to build modern, scalable web applications.
  • Enterprise Platforms (DXP): Architecting modular solutions within the Liferay ecosystem, specializing in OSGi modularity and Client Extensions.
  • Cybersecurity & Hacking: Junior Analyst path at Cisco Academy. Learning to think like a hacker to build resilient, "hardened" systems.
  • Game Development: Blending storytelling and logic. Check out my latest game project: The Lord of The Bricks.
