Building a web app begins by outlining user roles, primary scenarios, and the data schema. A strong MVP concentrates on 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 priority: performance budgets, caching, robust authentication, and clean API contracts. With effective monitoring, CI/CD, and deliberate architecture, teams can iterate quickly while maintaining codebase stability as features expand and traffic increases.
