Building a web application begins by outlining user roles, primary scenarios, and the data schema. A robust MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling the product to release swiftly without becoming a brittle collection of bespoke screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching, secure authentication, and clean API contracts. With effective observability, CI/CD, and well-planned architecture, teams can iterate more rapidly while maintaining a stable codebase as features and traffic expand.
