At UBS, I connect business stakeholders with engineering on data and analytics initiatives, turning requirements into scoped delivery and reusable data pipelines on Databricks and Azure. I also built proof-of-concept agent workflows with LangChain and LlamaIndex to show how GenAI could automate analytics and operational tasks.

Previously at UBS, I delivered risk dashboards and exposure reports for senior management and regulatory reporting, using SQL to analyze enterprise datasets and reconciling outputs against source systems. As an Internal Auditor, I led technology and IT operational audits and built Power BI dashboards to track control deficiencies and remediation progress.
