➢ I made significant contributions to the development and maintenance of the main site of guokr.com, a popular Chinese social networking website focused on popular science education. After two years of intense coding, I have developed a strong proficiency in Python programming skills, along with some frontend knowledge of JavaScript. Most importantly, I have gained a comprehensive understanding of how simple microservices can collaborate to form a complex system.➢ As a startup company, in addition to working on the main site, I also assumed the role of lead programmer to design and develop backend services for several startup applications that have the potential to determine future market directions.➢ Language: Python/Nodejs➢ Framework: Flask/Sqlalchemy/Gevent

➢ I participated in the software design and development of distributed backend services for a massive multiplayer online web game system, with Flash as its frontend. The business logic of the game system could be highly complex and had strict performance requirements for instant responsiveness. Throughout the project's design, I realized that a single-threaded application could still be highly performant and capable of supporting numerous online users simultaneously, given the appropriate architecture.➢ I contributed to the overall success of the game from the ground up, and it has been unexpectedly online for almost a decade, remaining accessible even today.

This showcased the advanced capabilities of our tech group, especially considering that Redis was not yet popular at that time.➢ Language: Java➢ Framework: Mina(long-polling)/Hibernate
