What was the most extensive project in terms of scale and implementation time for you?

The most extensive project for me was a corporate portal for a large company, which included:

• Development of a user and role management system.
• Integration with internal services and databases.
• Document management module with the ability to upload and search files.
• Implementation of a responsive interface using PHP with a framework.

The project lasted about a year, involving several stages: requirements analysis, architecture, development, testing, and deployment. The team consisted of 5 people, and I was responsible for the backend part and integrations. Such a scale allowed me to deeply engage in design and code optimization, as well as learn to work in a team and manage deadlines.
