Creating a web app begins by outlining user roles, primary use cases, and the data structure. A robust MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling fast delivery without becoming a fragile collection of ad hoc screens.

Post-launch, the emphasis shifts to scalability and dependability: performance constraints, caching strategies, secure login, and tidy API agreements. With effective observability, CI/CD, and well-considered architecture, teams can iterate rapidly while preserving codebase stability as features and user demand expand.
