Machine Learning Developer I at Inatel building Python AI services, LLM and RAG workflows, and clinical AI interfaces.

Brazil
Message

At Inatel, I build and maintain Python backend services and REST APIs for AI-enabled applications, integrating third-party services.

I develop LLM automation and RAG workflows with OpenAI APIs, LangChain, and LangGraph, using Qdrant or pgvector for retrieval. I also build document-processing workflows for PDFs and other unstructured data.

For clinical AI workflows, I develop React and TypeScript interfaces, train healthcare machine-learning models, and build Streamlit tools.

At Smart Sensing, I developed FastAPI REST APIs, helped with computer vision projects, and managed a computer vision project. I also worked as a teaching assistant at Inatel, developing AI code and API and UI tests.
