At QSpiders, I developed Java applications using Object-Oriented Programming concepts and Core Java. I also worked with Spring Boot on backend applications and REST APIs.
I used SQL and database connectivity concepts to perform database operations and manage application data, and practiced debugging and testing through hands-on development tasks.
On a project called NexaCart, I developed a full-stack e-commerce application with customer registration, product browsing, a shopping cart, and checkout. I implemented authentication and password encryption using Spring Security and BCrypt.
I also built REST APIs for product, cart, and order operations, and created an admin dashboard to manage products, customers, and orders. For my Banking Management System project, I developed REST APIs and implemented banking operations, transaction records, and validation.
