At Citi, I supported a global bank’s payments platform across 60+ applications, 20+ payment schemes, and four regions. I resolved production incidents through transaction-flow analysis and root cause analysis, and designed 100+ business-impact alerts to detect anomalies before clients were affected.
At ACI Worldwide (via iEnergizer), I supported the Postilion Real-Time Framework for banks, financial institutions, and consumer brands running POS networks. I diagnosed transaction-processing issues end to end and coordinated fixes with development, QA, and account teams.
