Building a web application begins by outlining user roles, essential use cases, and the data schema. A robust MVP targets main workflows, intuitive navigation, and consistent UI elements, enabling rapid delivery without evolving into a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching strategies, strong authentication, and well-defined API contracts. With effective observability, CI/CD pipelines, and well-planned architecture, teams can accelerate iterations while preserving codebase stability as features expand and traffic increases.
