About

I'm a Data Analyst with a B.Tech in Chemical Engineering and a Minor in Management from IIT Jodhpur, passionate about transforming data into actionable business insights. My experience spans SQL, Python, Power BI, Tableau, Excel, and product analytics, with a focus on solving real-world business problems through data. At Sepal AI, I enhanced Text-to-SQL AI models by validating complex SQL queries, reviewing business logic, and improving the accuracy of AI-generated analytical outputs. At IIT Jodhpur, I contributed to the development of an analytics-driven library management platform, where I helped define product requirements, built dashboards, and optimized SQL and MongoDB data pipelines, reducing API latency by 83%. Through internships and projects, I've worked on customer segmentation, cohort analysis, funnel analysis, KPI dashboarding, sales analytics, and user behavior analysis to uncover insights that support data-driven decision-making. I enjoy collaborating with cross-functional teams to translate business questions into measurable outcomes. Core Skills: SQL • Python • Power BI • Tableau • Excel • Data Analysis • Data Visualization • Product Analytics • Funnel Analysis • Cohort Analysis • KPI Reporting • MongoDB • Statistics • Agile I'm actively seeking opportunities in Data Analytics, Business Analytics, Product Analytics, and BI, where I can leverage data to solve meaningful business challenges and create measurable impact.
