Building a web application begins by outlining user roles, major use cases, and the data schema. A well-crafted MVP centers on essential paths, intuitive navigation, and consistent UI elements, enabling a launch that isn't bogged down by a patchwork of separate screens.

Post-launch, scalability and dependability take the front seat: performance budgets, caching strategies, secure authentication, and clear API contracts. With effective monitoring, CI/CD practices, and a well-thought-out architecture, teams can move quickly while preserving code stability as features and traffic expand.
