Flexible Telegram Bot Development

I need a Telegram bot built with enough flexibility that I can later decide exactly which job it performs—anything from sending scheduled reminders, welcome messages, or news updates to moderating group chats or handling simple customer‐support queries. What matters most at this stage is a clean, well-documented codebase (Python or Node.js preferred) that taps into the official Telegram Bot API and exposes an easy way for me to switch features on or off without editing core logic. An external config file, environment variables, or a lightweight admin panel are all acceptable; pick whichever keeps deployment straightforward on a standard VPS. Key deliverables: • Fully functional Telegram bot with modular command / message handlers • Simple configuration method to choose its role and message type • Clear README covering setup, environment requirements, and token management • Brief hand-over call or chat to walk me through activating different modes If you have prior examples of bots that broadcast messages, manage groups, or provide quick-reply support, please share a link or repo snapshot so I can see your style.
