First time monk player, completely lost on how to update build

This is the current state of the char https://poe.ninja/poe2/profile/jeremiasalmeida-7692/runesofaldur/character/Monkmias

I can comfortably clear T12 content and can complete T15s, although I usually die a couple of times, which is frustrating. Because of that, I mostly stick to T12–13.

My main issue is that the build feels like it's lacking a significant amount of damage. I understand that I don't have any +level gear yet, but it doesn't seem like that's the only reason the build feels weak or this would be the main update.

I'd appreciate any advice on how to improve or update the build. A better explanation of the build's core mechanics and how it's supposed to function would also be very helpful.
