What I'm looking for

I'm looking to build reliable data products and scalable data systems that help business teams make better decisions, improve operations, and access trustworthy insights independently.

At Nubank, I build Spark and Scala ETL/ELT pipelines and curated Debit datasets that standardize core metrics, support experimentation and KPI monitoring, and enable self-service analysis. I also improved key pipeline processing time by an estimated 47% and reduced monthly processing costs by approximately R$490,000.

Previously, I improved B2B and B2C conversion at GoShare through pricing analysis, A/B testing, and regression modeling, and built logistics optimization solutions at Jumper that reduced route execution time by 17%. Across consulting projects at Barrio Cloud Company, I've delivered market basket analysis, fraud detection, BI dashboards, and business systems for clients in retail, finance, agriculture, and construction.
