Message

At OSF Digital, I develop AI-powered features for company data analysis, information extraction, intelligent search, and automation. I build agent workflows that connect LLMs with backend services and domain-specific tools.

I designed and implemented tools for Model Context Protocol servers, including tool architecture, integrations, testing, and migration of existing agent capabilities. I also evaluate AI features with DeepEval and refine prompts, tools, and workflows based on evaluation results.

Before my current role, I developed backend services and integrated LLM capabilities with external data sources for intelligent search and conversational applications. As a Software Engineer Intern at OSF Digital, I developed FastAPI REST APIs and serverless applications on AWS.

As a Research Fellow in Bioinformatics / Data Science at CNPq, I processed and visualized biological datasets and developed a computational classifier for DNA sequences. At PET Informatics, PUCRS, I developed and maintained website features and participated in exploratory Computer Vision studies.
