Building a web app begins by outlining user roles, main use cases, and the data schema. A strong MVP concentrates on essential paths, straightforward navigation, and consistent UI elements, allowing the product to be released swiftly without becoming a fragile collection of ad-hoc screens.

Post-launch, scale and dependability take priority: performance budgets, caching, robust authentication, and tidy API agreements. With effective monitoring, CI/CD, and careful architecture, teams can iterate more quickly while maintaining codebase stability as features and traffic expand.
