Senior Business Analyst, Enterprise Data Issue Resolution – Finance at UBS (2023-10 – Present)

• Led root cause analysis on aged, high-complexity finance data issues, introducing lineage tracing into the analysis method and deep-diving the GEAR database to identify the attributes and mappings needed to analyze data flows and pinpoint gaps; proposed resolutions adopted for several of the issues.
• Built a reusable data flow template that renders end-to-end system interactions on a single page, making it far quicker to see how data moves through the systems before an investigation begins.
• Resolved an FRB-exam-related issue by summarizing client data and identifying the mapping across 20 client data feeds, unblocking investigation of client-related findings; validated non-profit entities against IRS and public non-profit registry sources.
• Adopted and enhanced three enterprise Power BI reports — Taxonomy Scan, Cross-Divisional Impact, and EDIR Data Issue Progression — now used across 15 divisions and functions for a live view of issue status, cross-divisional exposure, and remediation progress.
• Run the monthly EDIR working group and present progress to Finance stakeholders; built and rolled out the centralized audit-trail template that now evidences every data issue progressed across five divisions.
• Ran the founding analysis for the Finance KDO domain working group: quantified concentration across key data outputs, key data elements, reporters, and applications; segmented data issues into agreed themes; produced from scratch the finance data flow diagram highlighting issues by status and theme; produced the metrics feeding the Finance team's business value report.

Senior Data Analyst, Investment Banking Governance at Credit Suisse (2019-12 – 2023-09)

• Created and owned the inventory and metrics for ~2,000 key data elements across 38 CUSO key data outputs, covering CUSO data across all business lines and reconciling directly with Risk, Finance, and Compliance program managers in each function — delivered under the firm's CUSO Data Strategy commitment to improve data quality.
• Designed and delivered the CUSO Reporting Database in 2 months — built in MS Access on Collibra metadata extracts, with table connections and the full SQL layer authored end-to-end — after Collibra's complexity and limitations made it impractical to combine the required lineage data.
• Created the CUSO exception report tracking 19 distinct data quality issue types (unpublished assets, control gaps, missing ownership) across every CUSO division and function, in response to inaccurate data surfacing in DataHealthDashboard, the main CUSO report, caused by inadequate key assets.
• Raised ~3,000 exceptions over 3 years and drove them to 97% resolution, running the bi-weekly CUSO CDO meeting across 10 functions (IB, CFO, CRO, GOPS, CCO, CIO, AM, WM, HR, GBSS) — reviewing open status, issuing new exceptions with clear remediation guidance, and escalating blocked items.
• Rebuilt that reporting framework as an interactive Power BI dashboard surfacing key data element lineage, primary KDEs and their underlying attributes per report, missing-ownership alerts, and control gaps on key elements.
• Produced variance analysis, trend reporting, and executive-ready narratives for senior management using Excel/VBA, Alteryx, and Power BI; authored playbooks and process specifications for recurring metrics and automated reporting.

Data Analyst and Program Coordinator at Legal Aid of North Carolina (2019-02 – 2019-11)

• Created data models and reports using SAP Crystal Reports and advanced Excel to improve visibility into program performance and case data.
• Performed data quality audits to assess accuracy, validity, and completeness of information used by the organization.

• Led financial report consolidation and due diligence projects under RAS and IFRS standards, supervising a team of three auditors across multiple engagements.
• Used SQL to extract and compare data across accounting, procurement, and warehouse systems, translating findings into actionable recommendations.
