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 rapid delivery without evolving into a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching strategies, strong authentication, and clean API agreements. With effective monitoring, CI/CD pipelines, and thoughtful architecture, teams can iterate more quickly while keeping the codebase stable as features and user demand expand.
