What types of applications have you designed: web, mobile, desktop?

I have designed various types of applications:

• Web applications: both single-page applications (SPA) using React and Angular, and multi-page with server-side rendering.
• Mobile applications: cross-platform on Flutter and native for Android and iOS.
• Desktop applications: using Electron for cross-platform solutions and WPF for Windows.

Each type requires consideration of user experience, architecture, and technologies.
