I don't know anything about the hiring process for designers, so just speaking to the programming side here. My first instinct was to look for a GitHub profile, both on the homepage of your site and alongside the various examples. The text field thing was interesting - why not put the code on GitHub, so it's easier for people to look through and try out? If it's already there, then make sure your GitHub profile is discoverable on your site, because I didn't find it despite looking for several minutes on multiple pages. Also consider posting your LinkedIn profile on your website (or get one if you don't have one). I personally don't care about that, but recruiters definitely seem to. In any case, my employer is actively hiring; I'll email you the job listings. Good luck.
