Building a web application begins by outlining user roles, primary use cases, and the data structure. A robust MVP emphasizes essential flows, intuitive navigation, and consistent UI elements, enabling a rapid release without evolving into a fragile collection of bespoke screens.

Post-launch, the focus shifts to scalability and dependability: performance budgets, caching, strong authentication, and clear API contracts. With effective monitoring, continuous integration/continuous deployment, and well-planned architecture, teams can iterate swiftly while preserving codebase stability as features and traffic expand.
