At Santander Digital Services, I contributed to a portfolio management application for Synthetic Securitizations within SCIB Banking. I developed Java/SpringBoot microservices connected through REST APIs and gRPC, and built Spark and Scala pipelines for batch and streaming data.

I also supported the AI-native transformation of corporate projects as an Agent Engineer, working with the AI Tech Lab within the Cosmos platform. Previously, as a Big Data Consultant at Bosonit, I contributed to the Graphenus platform and developed data pipelines in Azure Databricks.
