About Appyon
I build things that work, load fast and actually look good.
Appyon is the freelance business of Rick Korsten. I build interfaces that are technically solid and easy to use — with attention to speed, detail and code that's still readable a year from now.
I prefer working directly with clients or agencies, from a single job to a longer collaboration. Frontend is my speciality, but I'll happily jump into the backend with Node when a complete solution is needed.
