Nisha Sinha

I’m a data analyst with a BE in Information Technology, bringing hands-on experience in data analysis and machine learning. I focus on turning messy data into clear, decision-ready insights—especially through strong EDA, feature engineering, and model development.

In my Data Analyst Internship at Sevenmind Technology LLP (Nov 2023 / Mar 2024), I worked on churn prediction for banking by building a machine learning model with Python and SQL to identify at-risk customers. I conducted exploratory data analysis, addressed data imbalance, engineered key features to improve accuracy, and evaluated algorithms to support proactive retention strategies.

I also handled sales analytics, analyzing retail sales data to uncover trends and optimization opportunities. I built actionable dashboards in Excel and Python, partnered with stakeholders to assess performance metrics, and contributed to process improvements that achieved an 80% increase in inventory management efficiency.

I’m proficient in Python (NumPy, Pandas, Matplotlib, Seaborn, Scikit-learn), SQL (MySQL, SQL Server, PostgreSQL), and visualization tools like Tableau and Power BI. I’m driven by advanced analytical thinking and the goal of delivering measurable business impact with data-informed strategies.
