Here I am:

My name is Vikas Tandon and I have around 13 years of experience in the software industry. Currently, I am working as a Technical Manager. Although I have not used Spring Boot for around 1 year, I have prior experience with it.

I approached this technical assignment by starting with [fixing the issue in basic CRUD operation] (#1). This was crucial in ensuring that the core functionality of the system was working correctly.

I then utilized [DTO (Data Transfer Object) to communicate between the Controller and Service layers] (#3), allowing for clear and efficient communication between the different layers.

I also added [exception handling and returned appropriate HTTP status codes] (#5), to handle any errors or exceptions in a meaningful way and provide clear feedback to the user.

Next, I [upgraded the Spring Boot and Java version] (#7) to ensure that the system was using the latest and most secure version, which also provides better performance and bug fixes.

I also [protected the controller endpoints] (#9) to secure the system against unauthorized access and ensure data privacy.

Then, I [added caching logic for database calls] (#11) to optimize performance and reduce response times.

Lastly, I added [Swagger configuration for API documentation] (#13), which is essential for clear and concise documentation and effective communication and collaboration with team members and stakeholders.

Added logging(#16)

I am working on these open issues (#18, #17, and #15). Implementing unit tests, containerizing the app, and profiling for the development and production environments are important steps in ensuring the reliability, performance, and maintainability of the system.
