I’m a Data Analyst with 6+ years of experience in financial data analysis, visualization, and automation. I focus on improving data accuracy and enabling data-driven decision-making through rigorous data quality frameworks.

At American Express, I drive data quality initiatives by analyzing large datasets, identifying anomalies, and ensuring the accuracy and integrity of critical financial data. I design and maintain interactive dashboards using Power BI and Excel, and I use Python-based automation to streamline manual processes and reduce operational overhead. I also coordinate with cross-functional stakeholders to investigate and resolve data-related issues while managing incident work-flows for consistent service reliability.

Previously at Tata Consultancy Services, I worked on a data quality management framework (Qalibrate) leveraging complex SQL validation to detect and remediate financial data anomalies, with end-to-end incident management via ServiceNow. I also built applications using Python, SQL, and Flask, developed a Selenium-based news scraping framework, and contributed to cyber-forensics research by detecting attacks such as DDoS, ARP, DNS, and Port Attack using deep learning models deployed with Django.
