Developing a web application begins by outlining user roles, key scenarios, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and predictable UI components, so the product can ship rapidly without becoming a fragile collection of one-off screens.

After launch, focus on scale and reliability: performance budgets, caching strategies, secure sign-in, and clean API contracts. With good observability, CI/CD, and careful architecture, teams can iterate more quickly while keeping the codebase stable as features and traffic grow.
