Rerisson Moura

I’m a Senior Data Analyst with 8+ years of experience in BI and Analytics, specializing in building data-driven environments in low data maturity contexts. I turn complex datasets into strategic business decisions by designing end-to-end analytical solutions—from data pipelines to executive dashboards.

In my current role, I developed scalable data pipelines using Python (Pandas) and SQL, integrating multiple commercial systems and processing datasets with 20M+ rows. I built analytical applications in Python (Streamlit) and cross-selling dashboards used by 200+ professionals, supporting operations exceeding 160M+ annually and 30K+ active customers.

I focus heavily on automation and operational efficiency. I automated analytical and operational processes using Python and Power Automate, saving 50+ hours/month, and led a PostgreSQL migration from on-premises to cloud (Neon) to improve scalability and concurrent access for analytical workloads.

I also deliver measurable performance and revenue impact—implementing customer performance monitoring models with +50% performance increases and building promotion simulation tools that contributed to +30% financial return. I’ve consistently acted as a bridge between business and technical teams, translating data into actionable commercial insights.
