At AT&T, I architect and lead unified data ingestion, ETL, and cloud modernization programs across SharePoint, ADLS, SFTP, Oracle, Snowflake, Vertica, MySQL, and SQL Server.

I re-engineered the ASPEN tool using Python, Flask, and Snowflake, built automated data sync and UC4 deployment frameworks, and delivered multimillion-dollar cost savings through automation. I also lead cross-functional teams delivering integration projects, including SAP Ariba-to-VMAP and Data Lake pipelines.

Earlier at Oracle, I led Oracle E-Business Suite and Fusion ERP implementations, integrations, migrations, reporting, and technical delivery for clients across industries. With 24+ years in enterprise systems, I combine data engineering, application architecture, PL/SQL development, performance tuning, and team leadership.
