About Me

I am a Full Stack Software Engineer with 5 years of experience in software development, holding a degree in Systems Analysis and Development from Uninter, as well as a postgraduate degree in Computer Engineering and another in Data Science and Artificial Intelligence.

I work on developing frontend, backend, and desktop solutions, participating in the entire application lifecycle, from requirements gathering to production deployment and maintenance.

I have a strong focus on code quality, scalability, software architecture, and best practices. In recent projects, I have been actively working with applied Artificial Intelligence, especially in developing intelligent assistants and LLM-based solutions, using RAG and integrating with AI APIs.
