Loads fast, looks nice, responsive to zooming, clear and obvious what it is, and the designs showcased look great too. Since it's HN there should be some complaint, and the only one I have is that the "my story" page has an unnecessary fixed header that consumes vertical space. But generally, I approve!

Unless the reader clicks the link to your story page, there's almost nothing about you personally or specific details about you as a working professional. It could just be that the "About Yitong" blurb at the bottom is kind of generic blah blah "design is amazing" stuff (sorry). If you're actively looking to get hired for projects, I think that text should be something more like "get in touch if you X, Y, or Z; I work remotely or on-site in SF; I can do A, B, and C" or whatever, something that clarifies your situation and availability.

It's not much, but I'm pretty proud of how it turned out.

I tried to let my work speak for itself by keeping the visual flourish to a minimum. I learned a lot about using white space and typography to enhance a fairly minimal design.

This is really nice and clean, I've been blinded by unnecessarily heavy portfolios before, so this is a nice touch
