Multilanguage Tech?

I'm in Miami for the Winter Break, and chanced into conversation with a family that speaks Spanish and minimal English.

While trying to explain what I'm studying and what I'd like to do with myself after college, I had a lot of trouble finding the right words to describe what I do. I ended up using Spanglish, examples and sign language to make myself clear.

I'm fluent in Spanish, but I don't have the vocabulary for many of the things I do. How do I describe the intricacies of the Web, how I bought a domain and wrote my own Web site, blogging, and such in another language? I understand these things so easily in English, but I don't know how to translate them.
