Creating a web app begins by outlining user roles, principal use-cases, and the data structure. A robust MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling rapid delivery without evolving into a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take priority: performance budgets, caching, strong authentication, and clean API boundaries. With effective observability, CI/CD, and well-considered architecture, teams can iterate more quickly while preserving codebase stability as features and user load expand.
