BrazilWhat I'm looking for
I am a Support Engineer and BI/Data professional with 2+ years in technical and developer support contexts and earlier hands-on experience in database and ETL development. I specialize in troubleshooting ETL processes, data pipelines, API integrations, and reproducing requests with Postman, while leveraging Oracle PL/SQL, Snowflake, Alteryx and Python scripting to deliver reliable solutions and automation.
I bring strong ownership of tickets and documentation (Jira, Confluence), experience with CI/CD (Git, GitLab, Jenkins), and a customer-first communication style in English and Portuguese. I am adaptable to shift-based and occasional on-call support and have proven success in pipeline troubleshooting, performance tuning, and migrating workflows to cloud platforms.
