What alternative solutions have you proposed in projects that differ from colleagues' approaches?

In one project, where colleagues used a classic approach with a monolithic controller, I suggested splitting the logic into services and repositories to improve code readability and testability. This made it easier to maintain and expand the functionality.

In another case, instead of directly using SQL queries in the code, I proposed implementing an ORM (e.g., Doctrine), which reduced errors and simplified database migrations.

Also, I sometimes recommended using design patterns, such as the "Strategy" pattern for selecting data processing algorithms, which differed from the simpler but less flexible approach of colleagues.
