what is code and why do I need it?
It's what makes your clicks and touches, whistles and beeps, videos and uploads, text changes and stylistic flourishes GO.
I've coded thousands of projects -- extensive online systems spanning multiple domains, platforms and databases, tiny embedded applications running in standalone electronics, and everything in between.
Current website work all features an "invisible" back-end content management system that allows the client to edit their site pages, site outline, content motifs, custom maps, video and photographic galleries, etc. See BIM!
