At Kolektor UT, I worked as a data analyst in water resources, applying data analysis and agile methods to configure water fees. I also cleaned and refined databases.
I designed recovery strategies that increased revenue by 25% and prepared operational reports and dashboards to track indicators.
I tested integration processes, validated business rules and data integrity, and documented and followed up on issues with technical teams. I used Excel, Oracle PL/SQL, Power BI, and Jira.
