Description

What if I were the missing piece to your needs?

As a passionate backend developer, I work on both Java (Spring Boot) and JavaScript/TypeScript (NestJS, Express) environments to design high-performance and maintainable APIs.

With over 3 years of experience, I have contributed to the implementation of cloud microservices (AWS, Azure), both on new projects and on legacy systems requiring refactoring, corrections, and technical optimizations.

Certified Java OCP 21, Spring, and Kubernetes CKAD, I prioritize the quality, collaboration, and reliability of the solutions I deliver.

I am available to discuss your projects and see how we could work together.
