👋 About me

Backend developer focused on Python. I like turning manual, repetitive work into software: REST APIs with FastAPI, process automation (RPA/ETL), web scraping, and system integration — all backed by SQL databases. I also work with C#/ASP.NET Core (REST APIs and Worker Services). Currently pursuing a Computer Science degree at UERJ (Rio de Janeiro, Brazil). Open to remote opportunities.
