Career Profile
With over 6 years in the tech industry, my career spans a diverse range of experiences, from backend server development to cloud-native technologies. Great experience with Golang and Python based projects, I have also undertaken small projects in Rust, Lua, and JavaScript frameworks (Vue, Angular). My expertise notably extends to 2 years in cloud-native development, encompassing Docker, Kubernetes, and Openkruise, underpinned by a solid understanding of distributed systems and microservices.
I am currently enhancing my technical knowledge through a Master’s program at the University of Exeter, with an expected graduation date of September 2024. This academic endeavor is refining my skills and preparing me for the next stage of my professional journey.
In pursuit of my career objectives, I am seeking a full-time position that aligns with my background in backend development, cloud-native systems, and distributed architectures. I am eager to contribute to an environment that values innovation and challenges, continuing my growth in the tech industry.
Experiences
Network Team (2021): Maintained and optimized HAProxy and Nginx within the production environment, gaining extensive knowledge in network infrastructure and load balancing.
Elastic Compute Team (2022 - Jul 2023): Transitioned to Shopee’s core deployment platform, significantly enhancing its stability and functionality. Led the design and development of a new Kubernetes and Openkruise based deployment platform, designed for increased stability, efficiency, and flexibility.
Skills and Leadership Development: Advanced my expertise in Golang, Kubernetes, and cloud-native technologies. Enhanced abilities in teamwork, communication, problem-solving, project management, and technical leadership, contributing to key strategic initiatives.
Internship to Senior Role: Began as an intern in the infrastructure team at Hortor Games, a mobile/H5 game company in Beijing. Over four years, progressed to more significant responsibilities, contributing substantially to various technical projects.
Major Project - Game Platform Development: Played a pivotal role in developing and maintaining a new gaming platform, aimed at enhancing performance and stability over the existing system. This critical project, involving a year-long development phase, resulted in a successful launch.
Technical Implementation and Impact: Utilized technologies such as Microservices, advanced database solutions, Message Queuing (MQ), ETCD, Redis, and Kubernetes. The platform efficiently handled high traffic volumes, managing 100k QPS and 10k concurrent connections, while supporting 10 million DAU, 100 million MAU, and over 1 million daily transactions.
Professional Growth: My tenure at Hortor Games was marked by significant skill development and contributions towards the creation and maintenance of robust, high-traffic gaming platforms.

GoIM is a distributed instant messaging solution based on Golang and RocketMQ. It’s a high performance and high availability solution.
I’ve developed GoIM in 2021 and it’s still under development. It has passed the basic IM tests, but it still needs a lot of work to be done.
My main purpose of developing GoIM is to learn distributed system and Instant Messaging. I’ve occurred a lot of problems during the development of GoIM
and I’ve fixed most of them. It means I’ve learned something and improved my skills.
