I am an analytical, detail-oriented Data Analyst with hands-on experience in data cleaning, statistical modeling, and visualization. I leverage Python, SQL, Tableau and Excel to derive actionable insights that drive business decisions.

I have built predictive models and dashboards, including a customer churn model with 85% accuracy and interactive Tableau visualizations to inform retention strategies. I also developed recommendation systems and NLP-based chatbots that improved user engagement.

My background includes working with big data tools such as Hadoop, Spark and Hive, and I have experience configuring Hadoop clusters and executing MapReduce tasks for large-scale analysis. I combine technical competence with strong communication and problem-solving skills honed while providing L1/L2 technical support.

I hold a B.Tech in Information Technology and multiple industry certifications in Data Science & Machine Learning, network security, and web development. I am collaborative, eager to learn, and focused on delivering measurable impact through data-driven solutions.
