What I'm looking for

I'm looking to expand from production data engineering into AI engineering, building LLM agents and RAG systems with rigorous evaluation, reliable tooling, and measurable outcomes.

At Creditas, I maintain financial data pipelines and build AI tooling for the Data Team, including Claude Code subagents for dependency analysis, an internal Confluence RAG agent, and a cross-source data-validation CLI.

I've built data platforms across Creditas, Loja Integrada, Stone, and SmartFit using Python, Airflow, AWS, Spark, Databricks, Kafka, and Snowflake. As Loja Integrada's sole Data Engineer, I scaled Kafka and PySpark ingestion to billions of daily marketplace events; at Stone, I led a SQL Server-to-Snowflake lakehouse migration.

I'm expanding into AI engineering through agentic RAG projects with LangGraph, RAGAS, gold sets, and empirical chunking evaluation. My Brewmaster project tested 22 documented evaluation experiments to select retrieval configurations based on evidence.
