What methods and approaches have you used in software development in your practice?

In my practice, I have used several methods and approaches to software development:

• Agile (Scrum, Kanban) — for flexible project management with iterative delivery and quick adaptation to changes.
• TDD (Test-Driven Development) — writing tests before code to improve quality and reliability.
• CI/CD — automation of build, testing, and deployment to accelerate releases.
• Code Review — joint code review to improve quality and share knowledge.
• Modular programming and OOP — for structuring code and increasing its reusability.

These approaches help create maintainable, high-quality, and scalable code.
