I build automation and data pipelines that remove manual work. Python, n8n, Playwright, OpenAI/LLM integration, web scraping at scale, CSV/Excel processing, report and document generation. Recent work: WhatsApp + AI scheduling assistant (n8n + OpenAI), marketplace product research automation, bulk data cleaning for e-commerce imports. Engineering degree from ITA (Brazil top tech institute), operations background at Brex where wrong data meant wrong money. I scope tight, deliver fast, and show working output before talking about hours.
