I started working with the blockchain stuff since 2017. I was built the ICO gateway system (Tokenomy - https://www.tokenomy.com/). I also created the ERC20 token, created the API for the token distribution. Then, i moved to blockchain consultant company in Malaysia in 2018, and built several ICO gateway systems, and also built the SAAS public-permissioned storage by using IPFS, and multichain as the DHT. In 2018, I got opportunity to work in one of the logistics company that implemented ICON blockchain on their environment. Last, in 2019 , I created a stable token including all of the usage of the token for the whole environment for the company that runs in the medical sector called Radiologex which is based in California. Mostly i used multichain on this project. I am really amazed on the progress of DEFI sector, it's really change how's people see the use of the blockchain.
