I am a senior software engineer. That is according to the company for which I work. Daily, I am using reference resources from the web (Google search, Stack Overflow, Code Project, and so on) to paper and book (real, technical books, reams of print-out code listing or requirement documents, or virtual paper as in Kindle or PDF). I've been doing this stuff since the early 1980s. I'm in my 50s. I see the big picture. Many changes have come and gone in our industry of software science. I try to be agile. I call myself a software and systems solutions engineer.
