Creating a web app begins by outlining user roles, essential use cases, 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 bespoke screens.

Post-launch, scalability and dependability take priority: performance budgets, caching strategies, robust authentication, and clean API contracts. With solid observability, continuous integration/delivery, and deliberate architecture, teams can advance iterations quickly while maintaining codebase stability as features and demand expand.
