About me

I'm Yu Serizawa (@upamune, pronounced "oo-pah-myun"), a software engineer based in Tokyo, passionate about building high-performance distributed systems and enhancing developer experiences. I specialize in Go and have a passion for TypeScript, with a particular fondness for Go's simplicity and efficiency.

I consider myself a "yak shaver" - someone who enjoys diving deep into technical challenges and optimizing systems from the ground up. Currently, I'm developing SaaS solutions at LayerX, where I enjoy building software with a great team.

Outside of coding, I'm an avid podcast listener and co-host of "magical.fm", a tech podcast I run with my product manager colleague. Feel free to explore my projects and connect through the links below.

I'm passionate about Personal Knowledge Management (PKM) and productivity tools. Currently, I primarily use Capacities and Logseq, though I was previously a devoted RoamResearch user.
