My Projects:

Book Store This project I built using a variety of advanced technologies. The core backend is developed using Java 21, with the application structured around the Spring framework, specifically utilizing Spring Boot for rapid application development, Spring Security for robust authentication and authorization, Spring MVC for handling web requests, and Spring Data JPA for database interactions. MySQL 8 is employed as the relational database management system, with Liquibase managing database migrations to ensure smooth schema updates and version control. Technologies: Spring(Boot, Security, MVC, Data JPA), MySQL, Liquibase, Mapstruct, Lombok, TestContainers, Docker, AWS

Accommodation Booking Service In this group project, I focused on implementing Spring Boot Security to handle authentication and authorization, ensuring secure access for users and administrators. I also wrote comprehensive tests to verify the functionality and reliability of the application. Additionally, I was responsible for deploying the project on AWS, ensuring that it is scalable and accessible in a cloud environment. My contributions have been integral in enhancing the security, reliability, and scalability of the Accommodation Service Web Application.
