Web app development begins by outlining user roles, primary use cases, and the data model. A strong MVP pinpoints essential flows, intuitive navigation, and consistent UI building blocks, enabling the product to ship swiftly without becoming a brittle collection of tailor-made screens.

Post-launch, scalability and reliability take center stage: performance budgets, caching strategies, secure login, and clean API contracts. With solid monitoring, CI/CD processes, and thoughtful architecture, teams can move faster while preserving a stable codebase as features and traffic expand.
