At AT&T, I partnered with finance stakeholders to turn business processes and client requests into requirements and functional specifications for financial data platforms. I validated Teradata-to-Snowflake migration accuracy and helped modernize platforms without disrupting business workflows.
During monthly book close cycles, I audited system logs, diagnosed file transfer failures, and deployed fixes to stabilize the platform. I also created testing packages and reviewed release documentation, reducing operational risks by 30% during new code deployments.
