Senior Fullstack Software Engineer
Expert in designing robust Web applications and distributed architectures. Passionate about innovation, Clean Code, and creating scalable solutions capable of supporting millions of users.
Software Engineer with 4 years of experience, I am a fullstack architect passionate about creating high-performance and scalable Web solutions. My specialty lies in designing distributed architectures capable of supporting massive loads without compromising on latency.
My expertise covers modern frameworks like React and Angular, as well as solid Backend architectures under Node.js and Symfony. I also master microservices patterns, containerization, and CI/CD pipelines.
An adept of Clean Code (TDD, Design Patterns) and Agile/Scrum environments, I am used to working on complex and distributed architectures. I am also a technical leader capable of mentoring teams and ensuring operational excellence.
Leveraging cutting-edge AI tools to accelerate development cycles and ensure code quality. Expert in prompt engineering and integrating AI agents into professional workflows.
