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, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching, robust authentication, and clean API schemas. Through effective monitoring, CI/CD, and well-considered architecture, teams can iterate rapidly while preserving codebase stability as features and traffic increase.
