Joseph Fajen — Sr. Technical Writer

I’m a Senior Technical Writer with 20+ years of experience in developer documentation, information architecture, and AI-assisted content workflows. The work I care most about happens sitting with the engineers who build the systems I document — asking the questions that get past how something works to why it matters. I stay just as close to the developers who rely on the docs, because their experience is the test of whether scattered, half-documented knowledge has become a single source of truth they can search, navigate, and trust.
