I’ve been writing software and hardware documentation since the late 1980s — I’ve documented programming languages, written system administration guides, edited and updated software docs, and designed quick reference guides. My favorite type of project is when I have to make an extremely technical product seem easy-to-use for a non-technical audience, but I’ve also written quick reference manuals for compilers running on massively parallel computers, setup manuals for modems, translation guides for GUIs, and system administration manuals for large database systems.
