Profile

Working professionally since 1990 as a software developer, I’ve worked in various positions and with different team sizes; from a single developer and analyst to a member of a team of 15 people from 3 different companies working on the backend system of the largest Brazilian ISP.

Self-taught in different languages — I learnt BASIC by reading my MSX manual and Pascal by reading Turbo Pascal help system — I'm always trying to learn new things, either by following examples or by reading books about different languages and other development subjects, like clean code and agile methods.

Professionally, I’m always trying to expand my knowledge to different areas, systems and languages and the related processes.

I also organize three MeetUps in the Porto Alegre region: "PyTche" for Python devs; "Porto Alegre Clean Code" for discussing clean development methods and "Rust in POA" for Rust devs.
