I'm a web programmer and consultant (but not a graphic designer). I'm an expert at diagnosing cross-browser CSS display issues in screen stylesheets, including responsive ones for supporting mobile devices, like smartphones. My specialties also include writing lean, cross-browser compatible JavaScript/DOM scripts (with Vanilla-JS or jQuery) and writing valid, semantically correct HTML5. Techniques for optimizing the loading speed of web pages, usability/UX, and accessibility are other areas of interest for me.
