I need a Telegram bot focused on user interaction, not heavy business logic. The entire experience must revolve around a clean menu system that opens with /start, presents clear options, and drills down into sub-menus without breaking the chat flow. For now, each button can return a placeholder message; the priority is proving the UI framework so I can later attach automated responses, forwarding, or scheduling features on my side. Make the menu tree easy to edit from code or a simple config file, and ensure it can grow without rewriting core logic. Deliverables • Complete source code for the bot—Python, Node.js, or another well-supported language. • Deployment guide for a typical VPS or Heroku-style host. • README showing how to add or rename menu items and sub-menus. Acceptance test: starting the bot reveals the main menu; selecting an item opens its submenu; a Back option returns smoothly to the previous level. A short demo video or test bot link confirming this flow will speed up approval.
