Looking for a chess partner/group to improve

Hii all. I am rated around 2250 on chess.com rapid, I am working on opening-middlegame and looking to gain strength (preferably upto 2100 FIDE is my goal as of now)

I am quite good with the London and Caro-Kann, However, I need help with black openings against , like facing catalan etc, I have tried Semi-Slav, Grunfeld, KID, with not much success. I am willing to go for some opening which is moderate on theory and gives good winning chances.

So that was all about me, HMU if you are interested in working together on such specific opening, I am willing to work or KID/Grunfeld/Semi-Slav or something else, upon your suggestion. (Preferred ELO range ~ 2100 to 3400 on chess.com)
