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

Post-launch, the priority is scalability and dependability: performance budgets, caching strategies, robust authentication, and clear API contracts. With effective monitoring, CI/CD pipelines, and well-planned architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
