I am software engineer form the eu and I hat everything they doing in tech. Really considering learning.

Hey there I hated to use complicated crashlytics solutions like firebase crashlytics or sentry and in the end I didn't even get redux state or last react navigation path out of it. That's why I decided to make my own lib specialised only on React Native with some of the most used libraries. I hate overengineered stuff, so I've tried to make the implementation as easy as possible, so you can use the lib with only three lines of code. If you are interested to try it out, than write me an email at vankatadam@gmail.com or fill the google form at my landing page and I will invite you to try my project. I would love some feedback from you!

Based on your phrasing, and that you and adamvankat list the same email address, this isn't your friend's work - it's you using two accounts.

how is it legal to use private apis of another company in your product? does it not count as cyber attack or potential dos?

you have to be in the same network? how is it a airdrop alternative? At least for me I use airdrop most of the time when im not in a local network.
