Building a web app begins by outlining user roles, main use cases, and the data schema. A sturdy MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, allowing the product to release rapidly without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability take center stage: performance budgets, caching, secure login, and clean API agreements. With effective monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while maintaining codebase stability as features and demand expand.
