Building a web app begins by outlining user roles, essential use cases, and the data structure. A strong MVP emphasizes core pathways, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a collection of unreliable, bespoke screens.

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