Don't overcomplicate it.

- Build a Bank Account System to learn OOP, inheritance, and polymorphism done properly
- Build a Library Management System to practice CRUD, collections, and file persistence
- Build a TCP Chat App to understand sockets, threads, and blocking I/O streams
- Build a Task Scheduler to master executors, thread pools, and Java concurrency
- Build a Simple HTTP Server to work with raw sockets, request parsing, and response logic
- Build a Student Grade Tracker to use Java Streams, sorting, and functional-style pipelines
- Build an Inventory System with JDBC to learn database integration from first principles
- Build a Dependency Injection Container to go deep on reflection, generics, and annotations

The best way to learn Java? Projects. Not tutorials.

Junior developer uses Controllers.

Middle and Senior developers use FastEndpoints, Minimal APIs, MediatR, CQRS, AutoMapper.

Architect uses Controllers again.

Why does this happen?

Because real-world projects benefit most from simple solutions.

Junior developers typically start by writing Controllers because they’re straightforward and easy to get started with.

Middle and Senior developers explore tools like FastEndpoints, Minimal APIs, MediatR, CQRS, and AutoMapper.

They see the advantages of cleaner separation, reduced boilerplate, and elegant solutions.

But when you reach the Architect level, you realize that simpler solutions often win.

Controllers, despite being "basic" and "boring" often provide the clarity and simplicity necessary for efficient development.

The key lesson:
➡️ Don't add complexity unless you really need it.

Small applications benefit using straightforward Controllers or Minimal APIs.

Medium-sized applications benefit from additional patterns like MediatR or CQRS for better organization.

Large systems might require Clean Architecture or Domain-Driven Design (DDD).

But always start simple.

You can add complexity later if the project really needs it. Until then, keep it clear, maintainable, and efficient.

Build step by step.
Focus on delivering business value, not complexity.
