Building a web app starts by outlining user roles, main use cases, and the data model. A strong MVP prioritizes essential flows, intuitive navigation, and consistent UI elements, so the product can be delivered quickly rather than evolving into a fragile collection of bespoke screens.

Once deployed, scalability and dependability are paramount: performance budgets, caching, robust authentication, and clean API contracts. With solid monitoring, CI/CD, and careful architecture, teams can iterate faster while keeping the codebase stable as features and traffic expand.
