Sobre mim

Cursando Ciência da Computação (IFPA) e Análise e Desenvolvimento de Sistemas (Uniasselvi), ambos iniciados em 2026. Em 2026 fundei o ecossistema KODAROS — e-books, ferramentas, softwares, sites e vídeos. Selecionado em processo seletivo para quatro bootcamps corporativos da DIO (169h no total: Bradesco GenAI 52h, Riachuelo 35h, Santander Excel+IA 29h, CI&T Java AI Copilot 53h), com um projeto publicado em cada um. Foco: pipelines de dados e ML em Python (pandas, scikit-learn), Excel/Power Query com IA no fluxo de trabalho (Copilot, Claude Code, GPT Agents) e interfaces React/TypeScript.
