Building a web app begins by outlining user roles, principal use cases, and the data structure. A strong MVP concentrates on essential workflows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of scattered screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, robust authentication, and tidy API contracts. With effective monitoring, CI/CD, and deliberate architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
