What methodologies have you used in your practice?

In my development practice, I have used several methodologies depending on the project and team:

• Agile (Scrum, Kanban) — an iterative approach with regular meetings and quick adaptation to changes.
• Waterfall — a traditional waterfall approach where phases follow sequentially.
• TDD (Test-Driven Development) — development through writing tests before code.
• CI/CD — continuous integration and delivery for automating build and deployment.

For example, in one project, we used Scrum with two-week sprints, daily stand-ups, and retrospectives, which helped quickly respond to changing requirements and improve the process.
