Building a web application begins by outlining user roles, main 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 fragile collection of bespoke screens.

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