👋 Hi, I'm Daniel!

Backend Software Engineer with strong experience in designing and evolving distributed systems using Java (Spring Boot, Jakarta EE) and Golang. At Itaú Unibanco, I work on large-scale modernization, transforming legacy monoliths into scalable, maintainable microservices using DDD, Clean Architecture, and SOLID principles.

I combine hands-on development with architectural guidance — covering API design, asynchronous messaging (Kafka, Camel), observability (Datadog), CI/CD pipelines, AWS infrastructure, and performance tuning.

As a committer to Apache TomEE and contributor to Jakarta EE and MicroProfile, I help improve enterprise Java runtimes and developer experience through open source contributions and community engagement.

Passionate about clean code, simplicity, and building software that evolves with the business.

💻 What I work on

I maintain open source repositories designed to help developers:

• Apply Clean Architecture, Hexagonal, and Layered Architecture using Jakarta EEFramework
• Build robust REST APIs with Jakarta MVC and JAX-RS
• Use Apache TomEE in production-ready microservices
• Structure real-world applications with good design practices
