About Me
I’m a hands-on IT “nerd” based in Metro Vancouver now. I have totally over 15 years of IT working experience in lots of different industries. Additionally, I am a quick learner and have an outstanding, self-motivated professional with more than 5 years of IT working experience in Vancouver, Canada, mostly focusing on Linux / Windows System Administrator / DevOps / Kubernetes Engineer.
Currently, I’m working in a high-tech company as an IT manager, in charge of everything IT related. Identifying IT problems, resolving IT issues, helping the users to accomplish what they want, and planning IT strategy is my daily life. I pretty enjoy every moment of success achieved through the efforts with the team and myself.
Apart from the infrastructure, I also like developing various apps including both back-end and front-end by node js, python, etc. In my spare time, I was fortunate enough to be part of a passionate, creative start-up team. Together, I participated in several interesting projects and not only responsible for the infrastructure design and implementation part but also some of the code developing parts.
I am always truly honor and proud of working with lots of excellent people in my life and learn from them. That makes me able to fit different roles in the job.
Projects
Massive Storage Provisioning (2020.04 - 2020.06)
Infrastructure Design/Implement/Support and DevOps
FreeNAS 11.3+ Synology NAS NetApp Samba Winbind iSCSI CIFS NFS
As the business grows, the team is eager for more storage. I adopted the two types of NAS for two different purposes through SAN. One solution is using Synology NAS with HDD disks provisioning the massive storage for data backup. The other solution is using Inspur server with NVME SSD disks flexibly shipping more spaces for the business data. I configured and operated the NAS with high availability, scalability, and security, distributed the storage by NFS, CIFS and iSCSI for different teams in the organization.
Container Orchestration & Automation (2019.10 - 2020.04)
Infrastructure Design/Implement/Support
Kubernetes (PV, Ingress, Helm) Jenkins Apache Groovy Harbor Rancher
The goal of the project is to set up an orchestration that helps the team more easily manage complextasks and workflows. To replace current Jenkins and about hundreds of virtualized Jenkins agents, I installed Kubernetes (kubernetes.io) that automates the container operations and scalable, as well as the Jenkins Kubernetes-plugin. For the Jenkins agent docker image, I set up the Harbor (goharbor.io) as the registry to deliver and manage the docker images across the multiple nodes. Now I’m still consistently doing the on-going support for this project, such as agent docker image build-up, pipeline configuration, performance monitoring, resource management and etc.
Crypto-currency FinTech Project Powered by Algorithm Trading (2018.09 - 2019.05)
Infrastructure Design/Implement/Support, DevOps and Full-stack Developer
Kubernetes (PV, Ingress, Helm, etc) Node JS VueJS Python MongoDB AWS TensorFlow
The project is a cryptocurrency asset management that helps clients grow digital assets through machine learning-based high-frequency trading products. As one of the founding members, my primary responsibility was designing and implementing the infrastructure from scratch for the computing of the machine learning in the cloud as well as the Node JS coding for data collection and crypto-currency trade through cryptocurrency exchange API. In the collaboration, I am also the DevOps, in charge of the workflow of the code development, testing, and auto-deployment.
Setup and Maintain a Node on the EOS Blockchain (2018.05 - 2018.09)
Infrastructure Design/Implement/Support
Kubernestes (PV, Ingress, Services, etc) Bare Metal Docker Image Build
Our team builds, ships and operates the solution of EOS nodes on bare-metal with high availability, scalability, security, and development experience. I’m one of the leading innovators, engineers, and thought leaders in the team. We innovatively combine the EOS node program with Orchestration that benefits building the EOS nodes by leveraging Kubernetes’ high availability, self-recovery from failures, distributed nodes, and rapid deployment. Apart from the technical hands-on, I have more conversations with the people from the different EOS communities and contribute more tech documents at the beginning of EOS go-live.

Direct Sale Virtual Assistant for Social Network Marketers (2018.03 - 2018.08)
Full-stack Developer
Node JS, Swagger Microsoft Bot Framework Google Cloud VueJS i18n MongoDB Scrum Board
The project is developed on the top of the WeChat platform but specializes in natural language processing and conversational user interface. Also, it’s the milestone in my IT career as a full-stack developer. My primary responsibility is the back-end coding interacting with WeChat’s official account API and payment API as well as the integration with Microsoft Bot Framework. Through the interpersonal interaction between the user and the WeChat official account, the conversation content is collected, processed by natural language, and the best answer that satisfies the user’s needs will be automatically returned to the user

More about me
When I was a 5 years old my mother always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up I worte down ‘happy’. They told me I didn’t understand the assignment, and I told them they didn’t understand life.
