Summary
AI Engineer at SEPLAG-MT. I also have over 6 years of experience in technology and artificial intelligence, working with a wide range of tools and frameworks, including Python, Pandas, Streamlit, and Plotly. I also leverage AI-powered approaches, including multi-agent systems with Agno, secure integrations through the MCP protocol, and LLM-based applications with RAG - Agentic, LangChain, CrewAI, and Agno. At SEPLAG - Secretaria de Estado de Planejamento e Gestão do Mato Grosso, I lead an AI team where collaboration and knowledge sharing are central to building innovative and scalable solutions.
Throughout my career, I have achieved key milestones, including the development of fully automated workflow systems that increased efficiency in legal processes by over 70%, the implementation of AI-powered chatbots using OpenAI and Ollama, and the leadership of projects that integrated institutional systems in government organizations. I hold a Bachelor’s in Computer Engineering, a Postgraduate degree in Artificial Intelligence and Machine Learning, where I completed intensive bootcamps in Python Development, ML Engineering, and ML Architecture, and two MBAs (IT Management and Databases).
My professional goal is to generate meaningful impact wherever I work, creating solutions that combine cutting-edge technology with operational efficiency and sustainable development. I am passionate about driving digital transformation, fostering innovation, and leveraging AI to solve complex problems that can improve organizations and society as a whole.

Senior AI Engineer
Secretaria De Estado De Planejamento E Gestão | SEPLAG-MT
08.2025 - Current
- Leading the AI team in developing a secure, first using an OpenAI API Key using gpt-3.5-turbo or gpt-4.1mini, and finally a locally hosted solution using Llama 3.1:8B within a Docker-Compose containerized environment, ensuring that no sensitive information is exposed externally.
- Adapted front-end architecture from NextJS to PrimeReact to ensure compatibility and seamless integration with organizational systems while maintaining responsive user experience.
- Through AI-powered “Generate” buttons, the system produces context-aware responses, reducing procurement cycle times from two months to just a few days, enabling the bidding process to be completed within legal deadlines.
- Continuous improvements include upgrading infrastructure with more powerful servers to support larger models, resulting in more precise responses.
- Developed a parallel project: an institutional chatbot, also locally hosted using Llama 3.1:8B, built with the AGNO framework and RAG-Agentic architecture through Website KnowledgeBase integration, LangChain, CrewAI, and Agno.
- Built a procurement-focused institutional chatbot using Llama 3.1:8B, AGNO framework, and RAG-Agentic architecture, integrating Website KnowledgeBase, LangChain, and CrewAI to deliver rapid, legislation-based responses to user inquiries.
- The solution includes a secure login interface for internal access control and management of user-created chat sessions, ensuring accountability and compliance.
- For data persistence and retrieval, it leverages PostgreSQL for structured storage and Qdrant as an asynchronous vector database, enabling efficient semantic search and contextual memory across conversations.
- As a result, the chatbot reduces research time by up to 90% compared to manual consultation, significantly improving efficiency, knowledge accessibility, and decision-making in critical procurement processes
