Data Analyst | Power BI • SQL • Python • DAX | Turning Data into Business Insights | Ex-TCS

About

I'm an analytical, detail-oriented data professional with enterprise experience at Tata Consultancy Services (TCS), skilled in Power BI, SQL, Excel, DAX, Power Query, and Python. I enjoy working with data end-to-end — cleaning and structuring raw datasets, building DAX measures, and designing interactive dashboards that turn numbers into clear, actionable business insights. Through self-driven projects, I've built a Retail Sales Dashboard tracking revenue, profit, and regional performance; a Financial Dashboard monitoring expenses and profit margins for executive decision-making; and a Marketing Campaign ROI Analysis evaluating channel effectiveness, conversion rates, and customer acquisition cost. I've also worked with Python (Pandas, NumPy, Matplotlib) on a Weather Data Analysis project, applying statistical analysis and data visualization to uncover seasonal trends. At TCS, as an Associate System Engineer on the IT Service Desk project, I supported enterprise users through incident resolution, access management via Microsoft Azure, and mailbox/permission administration through Exchange Admin Center — all within strict SLA standards. This experience sharpened my attention to detail, structured problem-solving, and ability to work effectively across cross-functional teams — qualities I now bring directly into my data analysis work. I'm currently looking for Data Analyst or Business Analyst opportunities where I can apply my BI, SQL, and analytical skills to solve real business problems and drive data-informed decisions. Open to connecting with recruiters, hiring managers, or fellow data professionals — feel free to reach out!
