Building a web app begins by outlining user roles, critical scenarios, and the data schema. A strong MVP concentrates on essential flows, intuitive navigation, and reliable UI elements, allowing the product to launch swiftly without evolving into a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, robust authentication, and clean API boundaries. With effective monitoring, CI/CD, and careful architecture, teams can iterate more rapidly while preserving a stable codebase as features and traffic increase.
