Senior🎓
Top SchoolLeticia Marchezi is an AI Engineer with eight years of experience building generative AI solutions that bridge research and production, currently driving GenAI work at TRACTIAN. She specializes in agent architectures, LLM integration, and conversational systems—having deployed Bedrock-backed chatbots, RAG pipelines, and FastAPI services in cross-functional enterprise settings. Her background spans both structured and unstructured data, from translating natural language to SQL for Databricks to engineering prompt strategies like chain-of-thought for robust model behavior. Academic research and internships (FAPESP, University of Sheffield) underpin her practical skills, including creating annotated corpora, running LLM experiments for low-resource languages, and optimizing HPC workflows. A strong communicator who presents directly to business stakeholders, she pairs rapid prototyping (Streamlit) with reproducible cloud deployments (Docker, AWS) to turn data into actionable products. Based in São Carlos, Brazil, she combines top academic performance with hands-on GenAI product delivery and a knack for translating experimental ideas into production-ready agents.
