IndiaWhat I'm looking for
I’m a Senior Market Data and AI specialist with 15+ years in Banking and Financial Services, specializing in data & AI governance, vendor cost optimization, exchange licensing, entitlements management, and AI-driven automation. I’ve led AI-enabled transformation initiatives to improve compliance, audit readiness, and operational efficiency, while managing Bloomberg, Refinitiv, exchange data, and index vendors as a primary contact.
I bring deep expertise in Market Data Licensing and Data & AI Governance, ensuring adherence to mandates including GDPR, MiFIDII, SEC, NIST, and EU ACT—backed by robust data integrity frameworks and governance tools. I’ve supported major exchange audits (NASDAQ, NYSE, CME, LSE), reconciled DACS entitlements and usage evidence, and modernized legacy market data systems by enabling migration to API-driven and cloud-enabled workflows; in Index Administration, I built SQL-based validation checks that improved data accuracy by 30%.
