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

Post-launch, scale and dependability take priority: performance budgets, caching, robust authentication, and well-defined API contracts. With effective monitoring, CI/CD pipelines, and well-planned architecture, teams can iterate more quickly while preserving codebase stability as features and user load increase.
