Fixed some minor word order, added some particles and capitalized where needed. I also broke a few run on sentences apart to flow better. Since you mentioned wanting to improve on technical writing, I changed the words "wanna" and "cus". The way you used them is actually correct, but you would not use them in a formal setting.

Words like "wanna" and "cus"/"cuz" can sound natural/native, but they're very informal (good for text messages in half-sentences, but not much more), so I've replaced them here. "Drastically" is technically correct here but sounds a little funny; something like "significantly" might sound more natural. "Other stuff like that" can also sound natural, but if you're following it with a clarifying phrase like "related to ...," it sounds less awkward if you leave off the "like that" and just say "other stuff related to ..." Hopefully this helps – nice writing on the whole!
