Build the world with AI
Moving with the technology,turning ideas into things.
Hi, I'm KunKunRed. I started out as a backend engineer at a big tech company and now work full-stack at an AI platform. I like moving with the technology: when something new shows up, I try it, and these days AI is simply part of my everyday toolkit. Outside work I like turning ideas into real things: apps and tools today, maybe games next. The tools I build, I try to open-source so others can use them too.

About me
A backend engineer turned full-stack who likes the new and keeps moving forward.
01
Embrace change
Technology keeps changing, so I change with it. I try new things early and keep what works; that is how AI became part of my everyday work.
02
Full-stack view
I started in the backend and now work all the way up to the interface. I like being able to take an idea from start to finish myself.
03
Curiosity first
Apps and tools today, games maybe next. I don't draw lines around what I build; if it's interesting, I start.
04
Open by default
I've built on so much open source that I want to give some back. Tools I make and lessons I learn the hard way get shared whenever they can.
