Building a web app begins by outlining user roles, main use cases, and the data model. A robust MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, the emphasis shifts to scalability and dependability: performance budgets, caching strategies, secure login, and clean API agreements. With effective monitoring, CI/CD pipelines, and thoughtful architecture, teams can iterate more rapidly while preserving codebase stability as features and traffic expand.
