What I'm looking for

I'm open to backend or AI roles, either remote or with relocation to the Netherlands, Spain, or Portugal.

At Shineray do Brasil, I built a conversational AI agent for lead nurturing that increased qualified lead generation by 40%.

I also built a PostgreSQL-backed lead distribution system serving 4,000+ leads across roughly 100 salespeople, with timezone-aware routing and quota balancing. My work included Python data pipelines connecting Meta Ads and Instagram Graph APIs to internal dashboards.

I designed an LGPD-compliant WhatsApp Business API qualification flow that kept LLMs out of sensitive data paths, and maintained high-performance landing pages on Cloudflare Pages with attention to Core Web Vitals and SEO.

Previously at SEMAD, I built a Flask and PostgreSQL order-management application and Python automations that replaced manual data entry. Outside work, I built DocuMentor, a RAG-based programming tutor using LangChain, ChromaDB, and Groq.
