Building a web app begins by outlining user roles, primary use cases, and the data schema. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without evolving into a fragile collection of bespoke screens.

Post-launch, scalability and dependability become the top priorities: performance budgets, caching strategies, secure login, and well-defined API contracts. With proper observability, CI/CD, and deliberate architecture, teams can iterate more quickly while keeping the codebase resilient as features and traffic expand.
