I have 4+ years experience in web-engineering, and React is my best friend.
Everything you mentioned above, I have done it so many times. I worked in team with more than 20 frontend developers, and we had review everyday.
Here's few examples of what I've done so far https://trade.onederx.com, http://volleyball.instat.com. And my github page https://github.com/, but it little bit outdated, bcs I didn't use it for long time.
So, I hope you will contact me, my skype - gloompi, telegram, whatsapp - +8613270018916.
