What I'm looking for

I seek roles leveraging audit analytics, automation and data engineering where I can build scalable solutions, lead small teams, and help clients reduce risk and increase efficiency.

I am a Senior Data Analyst with over 4 years of experience in audit and assurance, focused on analytics-driven decision making for Life Sciences, Healthcare, and Consumer sectors.

I design and execute end-to-end analytics solutions — from data acquisition and cleansing to visualization — using PySpark, Python, SAS, and SQL to uncover trends, outliers, and potential fraud.

I have led teams of 6–8 members, coordinated with Partners and Managing Directors, and delivered high-impact automations (Python and VBA) that dramatically reduced manual effort and improved accuracy.

My achievements include migrating SAS workflows to optimized PySpark, building client-specific Tableau dashboards and automation tools, and receiving promotions and awards for high-quality delivery under tight deadlines.
