I left school, my job, and moved 800+ miles in 2022 to write code full time.
That was definitely one of the best and most life changing decisions I've ever made.
I've learned a lot since then and still have much more to learn.

These days I build things because I find joy in making something someone else really enjoys using.
I get excited about reaching a level of polish that users don't even notice.

In a time where code is cheap I pride myself in taste and utility.
The best sticking point — in my limited opinion so far — is the way using your product feels.
So I want everything I make to simply feel the best to use.

If you want to build something cool or connect hit me up
we'll grab a coffee or beer in you're in Austin! 🤠🦇
