Because South Korea and China launched cashless promotion earlier and I can't speak in Japanese. So the company supports me to build an international new development team with different management mode and tech stack. Because my budget is limited, and the recruitment situation is not good. I can't make sure all stockholders support this plan, so I finally gave up. My jobs in this project are: 1. proposing a proposal to create a new team 2. writing position descriptions with the HR department 3. writing document test questions, interview with the candidates and report 4. to control the costs, I planned to recruit more graduates and had made detailed training plans 5. design the VIS of the new team with designer

Gopos is my personal POS project in Japan, cooperated with [NihaoPay](https://nihaopay.com) and [Ryo Trading Ltd.](http://lingrui.jp) The primary function of Gopos is to help merchants to receive RMB from Alipay, WeChat, and UnionPay through the same QR code and automatically convert to Japanese yen. The MPM part is somewhat similar to [CloudPay](https://cloud-pay.jp/mpm), but Gopay has a much lower rate. Besides, Gopos will provide CPM and the corresponding POS ipad app, and will also provide SDK for launching Alipay and Wechat Pay via mobile apps of merchants. Tech stack of this project is Go, go-echo, gorm, mariadb, redis, react, react-native, etc. Since GFW blocks gcp, this project is deployed on azure. Moreover, it will start running in September 2019.

SquareMeter is a REITs-like asset securitization project that uses the decentralization of the blockchain and the tamper-evident factor to strengthen credibility to complete crowdfunding real estate investments, implement rental delivery, trading and derivative financial services.

We have a team of 14 programmers, 3 designers, 4 product managers, and a group of financial, legal, and administrative staff in the real-estate industry. My jobs in this project are: 1. software architecture design and tech selection 2. business, product, and financial model design, to ensure maximum reliability of the entire process, I tried to simulate the regulatory model of the real currency-issuing process in the decentralized structure 3. simulating the structure of the blockchain exchange, designing the trading, freezing mechanism, exchange, mortgage center, etc. 4. API design 5. for more easier to access to the blockchain service, I used php swoole to write a middleware based on the asynchronous task system 6. training a newbie frontend programmer in this project 7. using php swoole to write a lot of SDK 8. using solidity to write the smart contracts for this project 9. using web3 to write a php data interface server of geth for block information browsing Related tech keywords: php swoole, solidity, geth, nodejs, web3, redis, mariadb, react, mobx, react-router, antd
