Usefull Tech Stack - App, Frontend, Backend, Server

This is my "complex" techstack and now in production.

Principles of clean code, use of the best thing in one area and a clear separation of frontend and backend is important to me.

Server (Backend)

• Apache2
• PHP
• Mysql
• Symfony Framework (Api)

Frontend (Web)

• Twig
• HTML, SCSS, JS
• Used API
• Standalone

Frontend (App)

• Android (Native): Java -> WebView
• iOS (Native): SwiftUI

Now the ask: Why so complicated?
Answer: I think it makes sense to choose the best tool for each task.

Client and Server is in a perfect workflow.
