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

Post-launch, the focus shifts to scalability and dependability: performance budgets, caching, robust authentication, and pristine API interfaces. When paired with effective monitoring, CI/CD, and careful architecture, teams can iterate more quickly while preserving codebase stability as features and demand expand.
