Building a web application begins with outlining user roles, primary scenarios, and the data model. A strong MVP centers on essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, scalability and reliability take center stage: performance budgets, caching strategies, secure authentication, and clean API contracts. With effective monitoring, CI/CD, and thoughtful architecture, teams can iterate more quickly while keeping the codebase stable as features and traffic expand.
