What I'm looking for

I seek roles focused on building scalable ETL and analytics solutions, emphasizing automation, data quality, cloud platforms, and impactful reporting.

I am a data engineer and analyst with hands-on experience building ETL pipelines, migrating queries, and creating dashboards to enable better business decisions. I focus on automation, data quality, and performance optimization using Python, SQL, and cloud data platforms.

At Leega Consultoria, I developed Python ETL scripts, implemented data quality controls, monitored APIs and crawlers, and reprocessed failed pipelines to ensure reliable ingestion. At FK Partners and Igreja Universal do Reino de Deus, I prepared data, automated reporting (OTBI, Power BI, Analytics), and improved query performance and access controls.

I hold certifications in cloud and data technologies and pursue continuous learning in cloud platforms, Airflow, and BI tools. I am committed to delivering efficient, secure, and scalable data solutions that maintain integrity and support decision-making.
