What I'm looking for

I'm looking for an opportunity to analyze data, build clear visualizations, and contribute to data-driven products while growing my skills in Python, SQL, Tableau, and end-to-end data handling.

I'm building data-driven insights through Python, SQL, Excel, and Tableau. In my stock market prediction project, I cleaned historical data, analyzed trends and volatility, built a regression forecasting model, and presented results through interactive Tableau dashboards.

During my Java Developer internship at Technotech Nova Solutions, I designed relational database schemas and queries, strengthened API data integrity, and documented data-facing endpoints. I also built a full-stack healthcare platform with Spring Boot, Angular, and MySQL, reducing data retrieval time by 30%.
