Renan Matias

I’m a Python Development Specialist with over 8 years of technical experience and a strong business lens. I’ve delivered robust backend solutions at TOTVS and Grupo Globo while leading development efforts in Rio de Janeiro, Brazil.

At TOTVS, I led the development of scalable APIs using Python and Django REST Framework, and I architected complex ETL/ELT pipelines with Apache Airflow and Pandas to protect data integrity across business areas. I also implemented a quality-first engineering culture using automated testing with Pytest, reducing production bugs by 80% and preventing regressions.

I strengthen delivery with automation and integration: I built web scraping bots using Selenium to reduce manual operational time by 150 hours/month, and I created integration solutions between Python APIs and the SharePoint/PowerPlatform ecosystem to optimize corporate information flow.

Earlier at Grupo Globo, I modernized data architecture on GCP (BigQuery, Dataproc, Pub/Sub), migrated manual processes into automated big data flows, and developed dashboards plus data warehouse modeling for executive decision-making. I also built internal governance web applications (Python + JS/HTML) and implemented process automations with Power Platform, including support software in VBA and SQL for finance budget consolidations.
