At CI&T, I deliver data platform engineering for insurance and manufacturing clients. For an insurance and pension data platform, I reduced end-to-end processing from 3–4 hours to about 1 hour by optimizing Databricks workloads, and implemented reconciliation controls as a quality gate.
At Santander Brasil, I built and maintained ETL/ELT pipelines for a sales commission payment system and contributed to automating its processing. Earlier, I supported cloud migration work at Deloitte and Itaú Unibanco, and developed ETL processes as a Data Engineering Intern at Itaú Unibanco.
