Hey there, I'm Zefeng Wang, or, preferably just call me Wafer.
I guess you could say I’m kind of a programmer. My undergrad thesis was in that classic rite of passage for Chinese students: computer vision and deep learning. I’ve got some experience training neural networks. Right now, I’m doing research at Matsushima Lab at UTokyo, where I’m exploring how to blend transformer models with geophysics data—things like seismic and muon data. I've also done about half a year of backend development using Go, during which I followed a bootcamp to build an interactive blog website (different from this static one, since that one had full frontend-backend separation). I even tried writing a mini Go web framework like Gin, and of course, built a static HTML blog along the way.
These days, I like to dive deep into whatever catches my interest. Lately, it’s been my personal blog site—new tech always has a way of consuming my every waking moment. I’ve also made a daily habit out of LeetCode; if I skip a day, I feel restless. And since we’re talking Japan, of course I’m into ACG. I love all three—anime, comics, and games—which might be part of what drew me here in the first place. I dabble in everything from masterpieces to trashy isekai anime that are perfect for zoning out. For manga, I usually pick them up after falling in love with an anime adaptation… though I have to say, some authors really do go off the rails—shoutout to a certain Chizuru Mizuhara-led story. As for games, well, lately I’ve been in a bit of an “electronic ED” phase. Still, I’ve played a fair share of single and multiplayer games. My latest accomplishment was hitting Emerald rank on LoL Japan server a few months back.
And finally, the name Wafer. Back in my edgiest days, I used to go by Anemia—no idea why, I just thought it sounded cool. Eventually, I rebranded to wafer, kind of as a symbolic break from my chuunibyou past. The “wa” comes from my surname, and the “fer” from the second character of my given name. Why not the first? Well, my hometown has this naming tradition where everyone in the same generation shares a character—in my case, it’s “ze.” It kinda feels like a mass-produced middle name. I guess that tradition’s probably on its way out anyway.
