Full-Stack Developer
I design and build full-stack web applications with Java, Spring Boot, React, REST APIs and SQL databases, focusing on scalable architecture, clean, maintainable code and SOLID principles.
About me
My background, experience, and how I approach software development.
Hi, I’m Tomas Gabriel Cardozo, a Full-Stack Developer with a backend-oriented profile.
I have experience developing web applications, internal systems and databases, working with technologies such as Java, Spring Boot, PHP, Symfony, SQL and React.
I started my career maintaining and improving production systems, optimizing SQL queries and developing features for internal applications. That experience helped me understand the importance of building clear, stable and maintainable software.
I’m currently focused on creating modern, well-structured solutions by applying best practices in architecture, security, API design, authentication, database modeling and frontend-backend integration.
I’m also deepening my knowledge of microservices, cloud-native applications, Docker environments, DevOps practices and production-ready software.
I enjoy working on real-world problems, collaborating in remote or agile teams and turning requirements into simple, clear and scalable solutions.
