Building a web app begins by outlining user roles, primary use cases, and the data structure. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, so the product can be released rapidly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take priority: performance budgets, caching strategies, robust authentication, and clean API agreements. With effective monitoring, continuous integration/delivery, and well-considered architecture, teams can move faster while preserving codebase stability as features and user load expand.
