 ### Beijing Square Root Inc, Founder & Full Stack Engineer, 2016.07 - 2019.12
 
 - Beijing Square Root Inc. ran two businesses in 3.5 years. From July 2016 to September 2017, it rolled out and operated Fun Live, a knowledge live broadcast platform. From January 2018 to December 2019, it transformed into a software consulting business.
-- With Fun Live, users could participate in various knowledge lectures such as programming or design. Users could pay fees to attend live sessions or reward lecturers. The lecturer used the OBS tool to push live streams to the server. Users could participate in the lecture in real-time or see the playback later. The platform integrated seamlessly with WeChat for notifications. Hosted around 80 lectures, gained 30,000 users and millions of page views. Responsible for most software development and marketing, leveraging PHP, Vue, HTML, CodeIgniter, MySQL, Redis, LeanCloud, Alibaba Cloud, and WeChat SDK.

+- As a solo entrepreneur, I coded during the day and gained users at night; everything was direct with minimal bureaucracy. This was my peak performance. I registered the company, met with investors to secure an investment of half a million CNY, handled equity changes, attended other engineering conferences to reach out to potential lecturers, and built 10 WeChat groups with around 500 people each. The highs and lows were intense and exhilarating.
+- After getting investment, I hired 9 employees but had to let them go after two months, which contributed to one of my most painful mistakes: not having a long-term plan, wanting to impress others, and naively trying to train my management skills. The good news is that by hiring part-time engineers to do 50 small software projects together, we earned half a million back and gave it back to the investor when shutting down the company.
+- From an engineering perspective, I performed most of the software development, resulting in around 2,000 code commits across 3 web client apps and 1 server. They were open sourced on GitHub@lzwjava some years later. The project leveraged PHP, Vue, HTML, CodeIgniter, MySQL, Redis, LeanCloud, Alibaba Cloud, WeChat SDK, SRS (Simple Realtime Server), WeChat MiniProgram, Fabric, Linux, and Nginx. I also did some design work in Sketch.
 - During the software consulting business period, completed 50 small software projects for customers, including websites, games, and apps. The revenue was around 3 million RMB and the profit was around 700 thousand RMB. Responsible for project negotiation, team management, and some software development. Notable projects are shown below.
 - MianbaoLive: Led a comprehensive backend refactoring effort for MianbaoLive, a one-stop content monetization and social economy platform. Optimized the performance, stability, and user experience of the entire tech stack. Previously used ThinkPHP, Node.js, and Go, and rewrote everything in Laravel for server-side development. The platform included modules for courses, users, content, user attendance, payments, and distribution sales. Partnered with Himalaya, a top audio platform in China, and synchronized content between the platforms.
 - Jiangsu TV's Super Brain Program WeChat Mini Program: Responsible for all backend development and half of the frontend development for the Super Brain program’s WeChat Mini Program. Engaged viewers with interactive puzzle games, enabling them to compete and rank to become the "Super Brain." Used the WeChat Mini Program framework and Wepy (Vue.js) to create game components and ranking pages. Integrated RESTful APIs to fetch game data and user information. Performed extensive performance tuning to ensure the system could handle high concurrency, leveraging caching technologies such as Redis.
