I improve financial data systems, automate workflows, and protect master data accuracy.
PhilippinesWhat I'm looking for
At Citibank N.A. ROHQ, I led reference data BAU operations supporting financial systems across all asset classes, from bonds and equities to loans and mutual funds.
I helped automate the SMC-to-SECURE data flow by validating field mappings, tracing Bloomberg data, and participating in UAT. I also reduced a weekly reporting workflow from six hours to two through Excel automation and process redesign.
I maintained 99.9% data accuracy through source verification, cross-system checks, and audit trails, while resolving more than 20 urgent data exceptions daily. I investigate issues across Bloomberg, SMC, MSD, SECURE, and IMS and coordinate fixes with project and technology teams.
I've led and trained analysts across Manila, Olsztyn, and Buffalo, and bring earlier finance operations experience from B. Braun Medical Supplies and QBE Management Services. I'm also building my analytics capability through certified Excel, SQL, and Tableau training.
