Tell about the architecture — how you launched the project, what needed to be thought through?

When launching a frontend project, it is important to consider architecture with scalability, maintainability, and performance in mind.

Key points I considered:

• Project structure: dividing into modules and components to facilitate reuse and testing.
• Technology stack selection: for example, React/Vue/Angular, state managers (Redux, Vuex), bundlers (Webpack, Vite).
• Routing organization: to ensure smooth navigation and SEO support if needed.
• State management: planning which data will be global and which will be local to avoid unnecessary re-renders.
• Asynchronous operations: integration with APIs, error handling, and loading states.
• Performance optimization: lazy loading components, memoization, minimizing bundle size.
• Testing: setting up unit and e2e tests to ensure quality.
• CI/CD: automating build and deployment.

For example, when starting a project with React, I created a folder structure based on functional areas, used Redux Toolkit for state management, and React Router for routing. It was important to think about how components interact and how data is passed to avoid unnecessary UI updates.

I also paid attention to environment setup (development, staging, production) and integration with backend APIs to ensure stable application operation.
