At Davinci Technologies LATAM, I serve as Tech Lead on two GenAI products. I led a fintech document-processing system using Gemini on Vertex AI to extract structured data with 95%+ accuracy.

I architected its production pipeline on Vertex AI, BigQuery, and Cloud Scheduler, increasing throughput from 3 to 100 clients per hour. I also built a personalized AI marketing platform and a WhatsApp-to-Google Chat routing bot.

In a freelance project, I built and deployed a RAG-powered document Q&A API using Claude, FastAPI, and FAISS. My work also includes machine learning, data pipelines, and bilingual voice agents for appointment scheduling.
