Building a web application begins with outlining user roles, key use cases, and the data structure. A solid MVP emphasizes essential flows, intuitive navigation, and reliable UI building blocks, enabling a rapid release without turning the product into a fragile collection of ad-hoc screens.

Post-launch, growth and dependability take priority: performance budgets, caching strategies, robust authentication, and clean API boundaries. With effective observability, continuous integration/delivery, and well-planned architecture, teams can move faster while preserving code stability as features and traffic expand.
