Creating a web application begins by outlining user roles, primary use cases, and the data schema. A solid MVP concentrates on essential paths, intuitive navigation, and dependable UI elements, enabling the product to launch swiftly without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and reliability take center stage: performance budgets, caching, secure login, and clean API interfaces. With effective monitoring, CI/CD, and well-planned architecture, teams can iterate more quickly while preserving codebase stability as features and user load increase.
