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

Post-launch, the focus shifts to scalability and dependability: performance budgets, caching strategies, secure login, and well-defined API interfaces. Through proper observability, CI/CD pipelines, and well-planned architecture, teams can iterate more quickly while preserving codebase stability as features and user load grow.
