👋 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
