Who I Am

Toepper — Me

I love to build my ideas that live on the internet — with care, with craft, and with a healthy obsession for the details that make software feel good.

When I'm not working on my day job, I'm exploring emerging tech, sketching interfaces, or — evidently — summoning golems.

Frontend

From my point of view I have an eye for details and design, loving it to build fast, accessible, and delightful frontend experiences.

Design Systems

Strong aesthetic sense — because great software deserves an interface worthy of it.

Noteworthy

Not always technical, not always relevant.
