About

Me

I am a Data Analyst / Business Intelligence Analyst with hands-on experience in SQL, Power BI, Excel, and Python, focused on turning raw data into clear, decision-ready insights. I am currently pursuing a B.Tech in Computer Science (AIML).

I worked as a Data Analyst Intern at AtliQ Technologies, where I built 5+ interactive Power BI dashboards, validated 20+ business KPIs, and analyzed datasets with 50K+ records. My work helped improve reporting accuracy by ~25% and reduced manual reporting effort by ~30% through structured dashboards and automated calculations.

In parallel, I have delivered 8+ analytics projects across Finance, Sales, Marketing, Hospitality, Insurance, and Telecom, performing data cleaning, EDA, and KPI tracking. These projects enabled faster insight generation (30–40%) and supported data-driven decisions through stakeholder-ready dashboards and concise analysis.
