Developing a web app begins by outlining user roles, essential use cases, and the data schema. An effective MVP emphasizes core flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Once deployed, scalability and reliability become the top priorities: performance budgets, caching strategies, secure login, and clean API agreements. With proper observability, CI/CD, and thoughtful architecture, teams can move faster while preserving code stability as features and traffic increase.
