Hi,
I have the availability to work on this now. I program in several framework languages such as ruby on rails, nodejs, php and golang.
You can test this bot that I have in Telegram @classifiedsBot for a complete platform of classified ads. Still in development but you can try it to see my work. It is developed in NodeJs plus Postgresql among others.
Let me know more about what you need. I can do this job today.
Thank you.
