At BOAVISTA TECNOLOGIA, I optimized product data processing from over 2 days for 200,000 records to under 15 minutes for over 2.5 million records. I also designed and implemented the product’s Analytics data architecture, serving 100 companies and delivering analyses on over 2 million records in under a minute.
I developed an extraction, enrichment, and storage process in S3 with Apache Spark, bringing legacy data views into an integrated Data Warehouse. I also orchestrated pipelines with Apache Airflow and developed a REST API with Python, FastAPI, and PostgreSQL for strategic and executive decision-making.
At DATACOPER, I led an ETL versioning project that unified the ETL base across approximately 10 clients. I optimized Data Warehouse models and SQL queries, improving dashboard delivery speed by over 3x, and restructured ERP-based BI ETLs to reduce execution time from over 6 hours to under 1 hour.
Earlier, at IT7 SISTEMAS, I implemented Oracle Primavera P6 EPPM with Oracle BI EE while managing over 200 active projects. At CELEPAR, I contributed to migrating Paraná State’s fines system from a Mainframe to a Java and web-based platform; at AUSPEX, I led a team developing a desktop system integrating internal systems.
