Were all your projects developed from scratch or were existing solutions used?

Mixed approaches are often used in projects. Some projects are developed entirely from scratch, allowing for architecture and functionality tailored to specific tasks. In other cases, existing solutions, libraries, or frameworks are used to speed up development and leverage proven tools.

For example, when creating a web application, one might use a ready-made framework like Django, while writing the business logic independently. This approach helps balance efficiency and product uniqueness.
