Hello, I have experience with telegram bots, currently in test / development @classifiedsBot, a bot that allows you to create and search classified ads (USA only). You can try it and see what you think.
I propose to develop your bot in Node.js (javascript) but I can do it in ruby, php or golang, depending on your preference.
I propose to develop it in two parts:
1st delivery: Basic functionality and admin (will be administered by the same bot) for a milestone of 50% of the payment in 4 days.
2nd delivery: Complete functions for a second milestone of 50% remaining in 8 days.
Please take into account that I require you to create the two milestones in advance to accept the work.
I can answer all your questions.
Thank you.
