Student. Developer. Maker.
Callum Renner.
I like making things work — in code,
in hardware, and in the real world.



01 / A little introduction
About me
I’m an industrial engineering student at The Ohio State University who likes figuring out how things work, then seeing if I can make them better. That has pulled me into code, CAD, electronics, and plenty of hands-on projects.
I started learning Lua and C++ before AI tools became part of my everyday workflow. I use AI as a tool, not a shortcut, and I want to understand what I’m building, test ideas myself, and be able to explain why something works. That curiosity also makes it fun to connect people from different parts of a project.
It might sound a little too good to be true to say I enjoy all of that, but I definitely don’t know everything. I like putting myself in situations where I’m not fully comfortable yet — that’s where I learn the most and keep getting better.

Have something in mind?
Have an idea, a project, or just want to talk engineering? I’d be glad to hear from you.
