Creating a web app begins by outlining user roles, primary scenarios, and the data structure. A strong MVP concentrates on essential pathways, intuitive navigation, and consistent UI elements, enabling a release that's fast yet not a collection of fragile, ad-hoc pages.

Post-launch, scalability and reliability become top priorities: performance budgets, caching strategies, secure authentication, and clean API contracts. With effective monitoring, CI/CD, and well-considered architecture, teams can iterate quickly while keeping the codebase stable as features and traffic expand.
