I'm Davi, a Brazilian fullstack developer working at PicPay, where I build hierarchical forecasting models using a hybrid Prophet + LightGBM architecture. I work across the whole stack, from backend to data pipelines, and outside of work I publish open-source libraries, write on Medium, and I'm going deeper into offensive security: studying malware development, Windows internals, networking, and web security, while also exploring Rust, Go, and C#.
