Building a web app begins by outlining user roles, primary use cases, and the data structure. A solid MVP centers on essential flows, intuitive navigation, and consistent UI elements, allowing the product to ship promptly without becoming a brittle collection of ad-hoc screens.

Post‑launch, the focus shifts to scalability and dependability: performance budgets, caching strategies, robust authentication, and tidy API contracts. With effective monitoring, CI/CD, and careful architecture, teams can iterate more quickly while preserving codebase stability as features and user demand expand.
