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

Post-launch, scalability and dependability take priority: setting performance budgets, implementing caching, securing authentication, and maintaining clean API contracts. With effective monitoring, CI/CD practices, and deliberate architecture, teams can move faster while preserving codebase stability as features and user demand expand.
