Web application development begins by outlining user roles, primary scenarios, and the data model. A solid MVP concentrates on essential flows, intuitive navigation, and predictable UI elements, so the product can be released quickly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and reliability are the top priorities: performance budgets, caching, secure authentication, and clean API contracts. With proper monitoring, CI/CD, and thoughtful architecture, teams can iterate more rapidly while preserving the codebase stability as features and traffic expand.
