Jinka Shiva

I’m a Computer Science graduate and Java full-stack developer intern, focused on building reliable software solutions that turn data into clear outcomes.

In my internship, I developed a full-stack Employee Management System with Java, Spring Boot, Angular, and MySQL, designing and consuming 12+ REST APIs for secure CRUD operations. I also built responsive UI components with form validation, search, and pagination, while optimizing database queries for better performance.

On the analytics side, I built an end-to-end sales analytics and predictive intelligence pipeline that transformed 5,000+ transactions into analysis-ready datasets. I developed ML models including Random Forest churn prediction (85% accuracy) and sales forecasting for 12-month revenue, and I created Power BI dashboards for $2.6M sales with KPIs like profit margin (47.6%).

I also enjoy building practical, user-facing systems, like a weather forecasting application using Django and REST APIs with a mobile-first interface. By adding error handling, caching, and rate-limit protection, I reduced external API requests by 65%, and I continue expanding my engineering depth through tools like AWS Cloud fundamentals.
