Telegram Bot & Database Integration

I need a reliable Telegram bot that can store and retrieve data from a persistent database so I can keep track of users, their requests, and any information the bot collects along the way. The core idea is simple: a user interacts with the bot, the bot writes to—or reads from—a database, then responds instantly. Here is the scope in plain terms: • The bot should handle standard Telegram interactions such as /start, /help, and at least a few custom commands that I will outline once the project begins. • Every meaningful interaction must be written to the database so I can view or analyse it later, and the bot should be able to fetch specific records when prompted. • I’m open to either SQL or NoSQL solutions—advise me on what best suits scalability, low-maintenance hosting, and straightforward backups. • Clear documentation in English is essential so I can deploy the bot on my own server after delivery and tweak basic settings without calling you every time. Once complete, I will test it with real users; if everything works as described—no data loss, no crashes, command responses within a second—I’ll mark the job done.
