Instead of inviting people to contact you via Telegram, why don't you try to build trust from this forum? It will give you a reputation if you really have 8 years of experience.
We can ask questions, discuss and share with each other. And if you can provide what the members here need, wouldn't that also give you a reputation?
But good luck, @OP. Remember you are using Telegram, where many people are getting scams from people who use Telegram. No offense, @OP, because this is what has been happening all along.
Hopefully, you can think again about inviting people to contact you on Telegram.
