kalvin.io is currently directly accessible from within China, pages load quickly, and there are no intrusive ads for a completely clean experience. However, the site is built solely for personal professional showcase, does not offer any public products or commercial services, so its functionality is relatively limited.
This site is only suitable for recruiters who need to learn about Calvin's professional background, or fellow technology professionals who are interested in his personal open-source projects.
