about

background

I'm a full-stack developer with a degree in Information Systems from UNIBAVE. I'm interested in software engineering, internal products, backend, data, and systems that help teams organize real operational processes.

I started my career as a trainee at COPOBRAS S/A, working on the legacy ERP in Oracle/PL/SQL. At the end of my graduation I moved into a junior developer role, working on modules of the corporate system and on smaller projects like a Node.js automation to display reports on internal TVs.

Today I work as a freelancer. My main focus is the Charme Eventos management system, a platform in production that centralizes operations for a graduation events company. It's the project where I've learned the most about what it means to deliver software for a real client.

I'm open to returning to the tech industry full-time, with the experience of having taken a system from zero to production.
