Building a web app begins by outlining user roles, main use cases, and the data structure. An effective MVP centers on essential flows, straightforward navigation, and reliable UI building blocks, allowing the product to launch swiftly without turning into a brittle assortment of bespoke screens.

Post-launch, scalability and dependability take precedence: performance budgets, caching, robust authentication, and clean API contracts. With solid monitoring, CI/CD, and deliberate architecture, teams can iterate more rapidly while preserving code stability as features and traffic expand.
