Building a web app begins by outlining user roles, essential scenarios, and the data schema. A robust MVP concentrates on main workflows, straightforward navigation, and consistent UI elements, enabling the product to launch swiftly without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take priority: performance budgets, caching, secure authentication, and tidy API contracts. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while maintaining codebase stability as features and demand expand.
