Building a web app begins with outlining user roles, key use cases, and the data schema. A strong MVP centered on essential flows, intuitive navigation, and consistent UI elements enables rapid delivery without evolving into a collection of fragile, one-off screens.

After launch, the priorities shift to scalability and dependability: meeting performance budgets, caching strategies, secure login, and clean API contracts. With effective monitoring, CI/CD, and well-thought-out architecture, teams can move faster while keeping the codebase stable as features and traffic expand.
