Backend developer building Java and Spring Boot APIs, including an attendance system with six tested endpoints.

At Paarsh Infotech, I processed and cleaned datasets with NumPy and Pandas, then built preprocessing and feature engineering pipelines to support data-driven decisions. I also created Matplotlib visualizations to surface trends in sales data and collaborated on machine learning workflows.

I developed an Attendance Management System REST API with Java, Spring Boot, and MySQL, implementing CRUD operations and testing all six endpoints with Postman. My projects also include a Spring Boot and Thymeleaf task management app and a retail demand forecasting system using Python and Scikit-learn.
