I am a Data & Automation Engineer specializing in resilient data extraction, Brazilian public/B2B registries, and GPU-accelerated document processing.

  • 🏢 Brazil B2B & Government Data: Automated pipelines for CNPJ / Receita Federal, QSA, CNAE, PNCP Public Procurement (Licitações), Juntas Comerciais (REDESIM), and Judicial/Cartório records.
  • 📄 AI & RAG Document Parsing: Complex scanned PDFs, financial statements, and multi-column legal tables converted to clean Markdown & JSON using GPU OCR (Docling / Surya) and PyMuPDF.
  • 🛠️ Core Stack: Python, Go, Playwright / Patchright (anti-bot, Turnstile & mTLS A1 certificates), DuckDB, PyArrow Parquet, and NVIDIA GPU batch processing.
  • 🤝 Custom Enterprise Scrapers & Pipelines: Need a custom scraper, anti-bot bypass, or large-scale batch dataset? Reach out via my contact email or GitHub for a Proof-First 5-minute sample on your target data.
