Building a web app begins by outlining user roles, essential use cases, and the data structure. A strong MVP concentrates on primary workflows, intuitive navigation, and consistent UI elements, enabling rapid release without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take priority: performance budgets, caching strategies, safe authentication, and tidy API contracts. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate rapidly while maintaining code stability as features and demand expand.
