At Mix Alimentos LTDA., I led the implementation of an AI-powered OCR system that replaced manual entry of payment documents, using Google Document AI to read them and Gemini to interpret and validate the data.
I also designed the agent architecture and built a WhatsApp chatbot on the Claude API to classify why customers had stopped buying. It runs on Python and Flask on AWS, with automated tests and LLM evaluations covering realistic cases and prompt-injection attacks.
For Mix Alimentos LTDA.'s corporate portal, I worked across the development cycle and built most of a frontend component library, including a generic table used across 50+ screens. I also maintain a legacy PHP/Laravel system and have built projects including a payment document extractor and an online store.
