About

I have extensive experience as a developer (30+ years) using a variety of programming languages ​​as well as several databases (MSSQL, MySQL/MariaDb, Oracle, SqLite, MongoDb). I’m currently working with the .NET framework and Python, and I’m just starting out with Rust. My native language is Portuguese. I understand and speak some English. As an AI enthusiast, I found it interesting to lend my voice to training agents.
