Cloud-native architecture experience spans the migration of 100+ applications and 200+ data sources to AWS, Snowflake, and Redshift — with 35% agility improvement and full disaster recovery posture.

Core banking modernization with FIS IBS and TSYS achieved a 40% transaction-performance improvement and 99.9% reconciliation accuracy. In the Salesforce and Martech domain, an AI-powered email-to-case summarization system handles 80,000+ cases monthly, cutting agent handling time in half.

With more than $54 million in P&L accountability and leadership of 300+ professionals across North America, EMEA, and APAC, Thanikachalam brings executive-grade operational expertise. She has scaled data organizations from one to 200+ professionals and directs multi-million dollar vendor portfolios.

She advises CEOs, CROs, CIOs, and Board Technology & Risk Committees, and addresses board-level investment questions in AI ROI for the Board.
