RENAN MATIAS

I’m a Specialist Developer with over 8 years of technical experience and solid business acumen, with a distinguished track record at TOTVS and Grupo Globo. I lead the Rio de Janeiro, Brazil development of robust backend solutions and data engineering pipelines that connect real business needs to scalable delivery.

At TOTVS, I provide technical leadership for scalable APIs using Python and Django Rest Framework, with a focus on code quality and long-term maintainability. I architect and orchestrate complex ETL/ELT data pipelines via Apache Airflow and Pandas, ensuring data integrity across multiple business areas.

I’m equally driven by reliability and measurable outcomes. I’ve implemented a software quality culture through automated testing (Pytest), reducing production bugs by 80% and preventing regressions, and I use TDD/Clean Arch and microservices concepts to deliver dependable systems.

My work also spans automation and cloud platforms, including Web Scraping bots (Selenium) that reduced manual operational time by 150 hours/month and integrations across Python APIs and the SharePoint/PowerPlatform ecosystem. Earlier at Grupo Globo, I modernized data architecture on GCP (BigQuery, Dataproc, Pub/Sub), built executive dashboards, and advanced finance automation—turning governance and reporting into streamlined, trusted workflows.
