11. Monitor and Maintain
Once an application is launched to production, the true engineering journey continues.
A professional engineer closely monitors server performance metrics, listens carefully to real user feedback, and patches operational issues as they arise. This post-launch phase is where software organically grows over time. Continuous maintenance ensures that the application remains secure, incredibly stable, and highly valuable to its audience.
