What type of projects are you most interested in: web, mobile, or backend services? Why?

I am most interested in backend services because they form the core of the application's logic and facilitate interaction between the client and server, as well as with databases and external services. Working with the backend allows for a deeper understanding of the system architecture, optimizing performance, and ensuring reliability and scalability. Additionally, automating backend testing often requires a comprehensive approach, which is interesting from a QA Automation perspective.
