Marco Kwok

Digital Data Enablement and Analytics Specialist @ Hang Seng Bank

About

I specialize in turning banking and digital behavioural data into strategic business impact. With experience across Citi, Bank of Communications, and now Hang Seng Bank, I operate at the intersection of data engineering, analytics, and digital enablement within highly regulated financial environments. Currently at Hang Seng Bank, I focus on digital data enablement and tag management — building structured tracking frameworks that ensure accurate customer journey analytics across digital platforms. By strengthening tracking governance and improving behavioural data quality, I help marketing and product teams make more informed, data-backed decisions. Previously at Citi, I engineered a 90-day predictive spending model that increased card migration conversion rates by 15% and delivered zero audit findings during a major regional migration initiative. My core expertise includes: • ETL Architecture • Predictive Analytics • Digital Tag Management • Banking Data Governance • Customer Segmentation Technical toolkit: Python, SQL, SAS, Hadoop, Hive, Tableau,Tealium If you're working on digital analytics, customer journey tracking, regulatory data governance, or banking transformation — I’d be glad to connect.
