ASAP: TELEGRAM BOT EXPERT (Lots More Work)

I'm looking for a Telegram Bot Expert who knows all the capabilities you can do with the API. Overtime I'll need several things like: Here is your interview that you get paid for if hired. Make this: ----- 1) integrating web apps into modals within chatrooms 2) making the bot respond to things that are more than /, for example if someone says a specific thing 3) Popup modals with native buttons 4) Billing of various types 5) Telegram Passport for websites, next will be to put it on a KanBan board Bot Setup: Register a new bot via @BotFather on Telegram. Secure the HTTP API token for the bot. Database Integration: Establish a database for user subscriptions, chat configurations, and whitelist management. Essential tables: users, chats, user_chat_subscriptions, and whitelist. User Interactions: On entering chat or bot initialization: All users are auto-muted, excluding those on the whitelist. A modal pops up prompting them to /subscribe for unmute privileges. /start: Display a welcome message detailing the association's mute policies and instructions. /subscribe: User opts in for unmuting in the chat. Add to user_chat_subscriptions. Automatically unmute. /unsubscribe: User opts out. Remove from user_chat_subscriptions. Re-mute user. Admin Interactions: /muteall: Silence all subscribed members. Validate admin status. Fetch subscribers and mute. /unmuteall: Restore voice to all subscribers. Validate admin status. Unmute. /whitelist [username]: Exempt a user from auto-mute. Add to whitelist table. Special Provisions: Trial Period: Detect specific usernames (defined in database or hardcoded). Grant them a 30-day mute-free trial. Post-trial, prompt for subscription. Middleware: Verify admin credentials before allowing privileged commands. On user message: If muted and not subscribed, send a private reminder to /subscribe. Track and record chat details like ID, title, etc. Error Handling: Alert if bot lacks permissions. Direct admins to adjust. Handle misuse or incorrect commands gracefully. Notifications: Confirm subscription/unsubscription to users. Update admins post-mute/unmute operations. Optimization: Employ batch operations for mute/unmute in large rooms. Periodically purge the database of obsolete chat records. Deployment & Maintenance: Opt for a reliable cloud service for bot deployment. Schedule routine database backups. Set up monitoring and alerts for bot health and unusual behaviors.
