Building a web application begins by outlining user roles, core scenarios, and the data structure. A solid MVP concentrates on essential flows, straightforward navigation, and consistent UI elements, so the product can ship quickly without turning into a fragile collection of bespoke screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, secure authentication, and clean API contracts. With effective monitoring, CI/CD, and a well-planned architecture, teams can iterate rapidly while preserving the codebase's stability as features and traffic grow.
