About

I'm a software engineer based in Caxias do Sul, Brazil, studying Systems Analysis and Development at Universidade de Caxias do Sul (UCS).

Through G9 CODE, I develop web applications for businesses in Brazil and the United States, including e-commerce platforms and an art marketplace. I also work in technical support at Cyncly, collaborating with international customers and teams in English.

I'm looking for software engineering opportunities where I can contribute to a product, learn from experienced engineers and grow within a team.
