Freelance Writing


Freelance Writing is a step I took several decades ago as I realized that I had a unique ability to work in that field. In the ever-evolving realms of science and technology, clarity and accuracy are paramount. As a seasoned freelance writer specializing in these fields, I bring a rare confluence of deep-domain knowledge and the art of storytelling. My work is characterized by meticulous research and an innate ability to distill complex, jargon-laden information into accessible and engaging content.

Moreover, the value I add extends beyond mere writing. With a keen understanding of the digital landscape, I ensure that my content is tailored for optimal online engagement, incorporating SEO best practices to increase visibility and impact. If that is what you require. My adaptability and versatility are evident through a diverse portfolio that includes everything from in-depth articles and engaging blog posts to technical documentation and AI-driven voice-over narration. Partnering with me means entrusting your content to a professional who is not only passionate about the science and technology sectors but is also dedicated to bringing your vision to light in the most compelling way possible. Whether the goal is to inform, persuade, or simply educate, I am the freelance writer who can help achieve that with finesse and authority.

Educational Writing

As a former software developer and college professor, I have been writing and explaining complex scientific issues for the last 25 years. I have taken on a lot of content writing gigs, and I focus specifically on these subjects: 

  • Environmental Science
  • Renewable Energy
  • Biology
  • Geology
  • Astronomy and Astrophysics
  • Artificial intelligence (AI)
  • Information Technology

Technical Writing 

My freelance technical writing has covered an extensive amount of critical work that is often left behind on many projects but is nevertheless one of the most important aspects of those. You can’t use what you don’t understand, and as much as AI would like to cover all these bases, sometimes it takes a human’s touch. I specialize in these forms of technical writing: 

  • How-to’s/User Guides
  • SOPs 
  • Documentation 
  • Wikis
  • Content Strategy
  • UX/UI Writing

Freelance Copy Writing

I also write non-technical content in several areas:

  • Health and Fitness 
  • Vegan food/lifestyle 
  • Gardening (see my older blog A Giant’s Footprint as an example) 
  • Finance/banking 
  • Real Estate 
  • Consumer Electronics
  • Blog Writing / SEO 

… And So Much More!

I am a polymath with endless curiosity and interests. If you do not see something here but would like me to consider it, please drop me a line, and let’s talk about it!

My Freelance Profiles 

Of course, no good freelancer worth their salt would go without a presence on the two most popular freelance sites. If you prefer these platforms, please don’t hesitate to contact me there.

  • Fiverr
