I'm primarily a freelance writer and narrative designer for video games (meaning I'm mainly a storyteller), but in the course of that work have tackled logistical and technical writing as well. I've done everything from writing industry-facing articles on the design process, to technical manuals, to sales copy for the games themselves (store descriptions, loglines, websites and ads).
I've also done writing for software as a service pieces - primarily Stacklist.com. I spent months interviewing entrepreneurs and tech-based business owners about the software they used to manage and grow their business, then consolidated that information into concise, honest summaries of each products' strengths and weaknesses.
