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

Post-launch, scalability and dependability take priority: performance budgets, caching strategies, robust authentication, and tidy API contracts. With effective monitoring, CI/CD, and careful architectural choices, teams can iterate more quickly while preserving code quality as features and traffic increase.
