Web application development 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 launch quickly without becoming a fragile collection of ad-hoc screens.

Once launched, scalability and reliability become top priorities: performance budgets, caching, secure authentication, and clean API contracts. With effective monitoring, CI/CD, and thoughtful architecture, teams can iterate faster while keeping the codebase stable as features and traffic expand.
