Building a web application begins by outlining user roles, main use cases, and the data schema. A strong MVP concentrates on essential flows, straightforward navigation, and reliable UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

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