Throughout my career at Claro Chile, I developed solid expertise in data management, cost control, and process optimization. I was responsible for maintaining and updating a critical SQL database of over 7,000 active services, ensuring data integrity and availability for payment control and billing processes. I also generated monthly strategic reports for management using SQL and SAP to facilitate decision-making on expenses and the billing cycle. My work included performing complex analyses by cross-referencing information from different databases, which led to a 2% reduction in costs by optimizing the service cancellation process. I monitored and compared paid versus provisioned expenses on a monthly basis, improving the accuracy of expense forecasting by 96%. I also identified and verified incorrect charges from suppliers, which resulted in the request of 120 credit notes and the cancellation of services, generating an annual saving of $30 million for the company.
