Work

UTOFUN, 2019-07 to now

UTOFUN is a real estate SaaS company. My role is a mix of Full-Stack Engineer, DevOps, and Engineering Manager.

I am responsible for AWS, Aliyun, a flask RESTful API, an Express GraphQL API, an Apollo GraphQL server, two Next.js servers, a React Native App, a 14GB MongoDB Atlas, 61GB self-hosted MongoDB, a 24GB AWS RDS, security policy, the distributed engineering team and report to our CEO.

In the beginning, I converted utofun.com from React SPA to Next SSR to improved Baidu search index count by 616%.

Then I started managing the whole distributed engineering team and built 优投房经纪人工具, a React Native iOS app, to help real estate agents.

The next thing is to build school pages, with our first living design system.

After that, I started a series of cost optimisation to reduce infrastructure costs, for example, reduce WordPress costs by 75% and reduce AWS costs by 54%.

EXOSITE, 2011-02 to 2019-04

EXOSITE is an IoT SaaS company. My role is a mix of Full-Stack Engineer and Lead Engineer.

I was responsible for a PHP RESTful API, jQuery front-end, a React SPA, and 19 Koa/Express/Phoenix/Laravel microservices and the distributed UI team.

In the beginning, I built a custom JavaScript dashboard system. At the mean while I grew five interns/juniors into competitive engineers.

Following that, I build the whole RESTful API for our PHP server.

Then I started managing the UI engineering team in Taiwan and built Murano UI. One year after that, I started managing the whole distributed UI engineering team. At the mean while, I grew a dozen of interns into junior engineers.

After that, I implemented an Elixir/Phoenix microservice to work with Alexa, Google Home and IFTTT.
