PT-BR

Curioso por tecnologia desde cedo, encontrei no desenvolvimento de software uma forma de transformar ideias em produtos. Hoje atuo como Engenheiro de Software Pleno, unindo Frontend (React/Next.js/MUI) e IA aplicada para resolver problemas reais.

  • 🧠 IA: Gemini/GPT no Vertex AI, LangChain, RAG; engenharia de prompts e avaliação de qualidade.
  • 🧩 E2E: de dados/APIs ao front; Docker/WSL, GCP (Cloud Run, VMs).
  • 🔤 NLP: classificação, sentimento, Q&A, sumarização e similaridade semântica (Transformers, Hugging Face, spaCy, NLTK).
  • 🎓 ADS + pós em Eng. de Software e Eng. de Dados; colaboração diária com Git/GitHub, CI/CD e documentação clara.
  • 🎯 Próximos passos: consolidar RAG em produção e evoluir para Sênior.
