Building a web application begins by outlining user roles, primary use cases, and the data schema. An effective MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without turning the product into a brittle collection of ad-hoc screens.

Post-launch, scalability and reliability take center stage: performance budgets, caching strategies, robust authentication, and clean API contracts. With proper monitoring, CI/CD practices, and thoughtful architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
