SMAbout Samuel
I am a Data Architect specialized in AIoT (Artificial Intelligence of Things) with a degree in Data Science from MIT and practical experience in industrial automation, remote monitoring, and orchestration of intelligent flows with n8n, ESP32, MQTT, and Supabase.
I have developed solutions for companies such as Ambev, Itaú, Vivo, and SENAI, integrating physical sensors, custom firmware, dashboards, and predictive alerts with generative AI (GPT-4, embeddings, and vector classification).
In addition, I act as a Designer of Intelligent Agents and MCPs (Multi-Channel Processors) to automate complex interactions with clients or internal systems. My agents combine RAG (Retrieval-Augmented Generation), context graphs, and deterministic logic to ensure accuracy, traceability, and full decision control.
I work with technologies such as Supabase Vector Store, OpenAI, WhatsApp Cloud API, and LangChain, creating assistants capable of responding, deciding, and executing tasks autonomously and consistently.
I'm looking to collaborate with companies that want to scale their operations through intelligent automation, AI-powered monitoring, and secure and efficient conversational agents.
