Senior data analyst improving risk data integrity through SQL, Python, automation.
IndiaWhat I'm looking for
I’m a detail-oriented Senior Data Analyst with 13+ years of experience supporting applications and running data operations in the BFSI domain. I’m known for turning messy datasets into reliable inputs for risk analytics—especially VaR and stress testing—through disciplined SQL-based validation and strong data-quality controls.
In my current role, I ensure Market Risk dataset accuracy and integrity across downstream systems, running systematic data validation and reconciliation checks that directly protect regulatory reporting. I perform root cause analysis on recurring data quality issues and implement preventive controls, reducing data defect recurrence by ~25%, while supporting end-to-end pipelines with SLA compliance.
Previously, at CitiBank, I analyzed 3+ years of incident trends to improve issueresolution time by 30% and built real-time monitoring dashboards in Geneos to track anomalies and KPIs. I also automated recurring operational checks with Python (reducing manual effort by ~40%), managed Smartstream TLM reconciliation workflows, and delivered stakeholder-ready reporting that translates technical findings into business impact.
