I am a Data Scientist. I have never written Solidity until @ethglobal in Singapore a month ago where I spent learning smart contracts. My plan is to go over the courses in cyrfrin.io and finish most of them before @ethglobal in Bangkok. 

I want to build a home-exchange platform on chain. I have the vision and sustainable business model. Any builders interested to join me?

Impressive journey! Your determination to learn Solidity and build a home-exchange platform is inspiring. I'm sure many builders will be interested in joining you. Good luck with your project!
