Portfolio
Most of my technical writing work is done under a non-disclosure agreement (NDA), so I am unable to share most of my past work or without approval from previous places of employment/clients publicly...
However, I do dabble in contributing to open-source project/software documentation when I can. I'd like to do more of this!
LinkStack
I host my own LinkStack instance. I contributed to the FAQ section of their Docs.
Safing Portmaster
I wrote a thorough "Getting Started" guide for Portmaster; it's not on their wiki, but they do link to where it lives on avoidthehack.com
Docs for Browser Comparison
While this is my project, I did also write this guide which largely functions as the documentation!
