What I'm looking for

I seek a collaborative, Agile team role where I can build scalable web applications, improve backend systems, and continue learning modern web and cloud technologies.

I am a web developer with a technical degree in systems development from SENAI and hands-on experience building dynamic web applications using Angular, React, NextJS, and TypeScript. I have expanded my backend skills with NodeJS, Express, NestJS and Golang, and I prioritize clean, maintainable code and collaborative work in Agile SCRUM environments.

In professional roles and freelance projects I have designed and implemented APIs, worked with PostgreSQL and MongoDB, containerized applications with Docker, and deployed services to AWS EC2. I have experience troubleshooting legacy JavaScript/React code while introducing modern TypeScript implementations to improve performance and maintainability.

I focus on delivering scalable, production-ready solutions, contributing to architecture, database modeling, and real-time features with SocketIO, and I enjoy continuous learning to adopt best practices and new technologies that increase project value.
