Building a web app begins by outlining user roles, main use cases, and the data schema. A robust MVP concentrates on essential pathways, intuitive navigation, and consistent UI elements, allowing the product to launch rapidly without becoming a brittle collection of bespoke screens.

Following launch, the priority is scalability and dependability: performance budgets, caching, secure login, and clean API interfaces. With effective monitoring, CI/CD, and careful architecture, teams can iterate more quickly while maintaining codebase stability as features and user demand expand.
