I have over 30 years experience as an Electrical Engineer, Technical Writer, and Documentation Manager. I worked in technical areas including avionics, systems integration, mobile software, SaaS. Several years ago I left the corporate world to care for sick parents. I supported myself building websites, writing technical “how-to” books, and leading online courses. Now, with family issues behind me, I have the time to take on some freelance clients. My atypical career path taught me to work well with a wide range of clients and audiences. Clients like Honeywell and Microsoft, McGraw-Hill and other book publishers, even pre-IPO startups. Audiences from computer beginners, to B2B buyers, to engineers building aircraft systems. I'm skilled at learning complex technologies like VPNs and cryptocurrencies. And I excel at turning that raw data into understandable content for a target audience. I am looking to contribute to projects that need these skills. I'm particularly interested in subjects that empower individuals such as online privacy.
