I'm a rotom.

I draw things, and sometimes write code.

There are some games I've made. There aren't many right now.

The "SED" part came from my top three Team Fortress 2 classes by play time.

The Soldier_engie-demo → SolEngDem → SED

Really long ago it was sometimes shortened to TSED.

The "4906" part partially relates to 4096

But it's really just 2¹² with the middle digits in Base 10 swapped.
You may see a lowercase h appended in some places, as in the one hexadecimal notation.

Create text in a small (4x6) bitmap font.

Create text in a less small (9x14) bitmap font.
