Hi, I'm Sherman Liu.
I am a Python backend developer with seven years of experience building production web systems.
My backend work spans REST APIs, microservices, MySQL, MongoDB, Elasticsearch, ETL pipelines, RabbitMQ, workflow orchestration, and CI/CD. With additional frontend and design experience, I can also deliver full-stack applications when a role calls for it.
I am seeking Python backend opportunities and am also open to full-stack roles. Learn more about my experience:

Education in Canada
In 2026, I completed the Interactive Media Design diploma at Algonquin College in Ottawa. The program strengthened my frontend development, responsive design, accessibility, photography, and videography skills, complementing my backend experience with the ability to contribute across the full stack.
If you’re interested in my life abroad, I’ve shared some reflections from my first year in Canada in this WeChat post: A Year of Study in Canada.
My Blog
I enjoy writing and sharing my thoughts. When working in China, I gave several presentations on frameworks we used in our projects, explaning how they work, such as Flask, Nameko, and received positive feedback.
In my web courses, I built several HTML and CSS projects, where I learned a lot about responsive design, accessibility, and media queries. I wrote several posts to share my takeaways from those experiences.
My Photo
Outside of work and study, I love backpacking. While working at Student.com, I had the flexibility to work remotely, which gave me the opportunity to travel to over 20 provinces in China. I'm also passionate about photography and videography. I've taken many photos during my trips, and I've used some of them as banner images on my blog posts.
