Have you worked on projects that are used internally within the company, i.e., internal projects?

Yes, I have experience working with internal projects that are used within the company. Such projects often have the following features:

• Focus on integration with internal systems and processes.
• A narrower user base, which allows for faster feedback.
• Often fewer requirements for scalability and security compared to public products, but higher requirements for stability and ease of support.

For example, I participated in the development of an internal resource accounting system that helped company departments optimize costs and plan purchases. This allowed for quick implementation of changes and adaptation to business needs.
