API Technologist / Tech Journalist

Hi, I'm Bill Doerrfeld, a tech journalist. My beat is the web API economy. I study Application Programming Interfaces, analyze the tech industry, and share insights through evergreen articles on high impact topics. I live and work in Seattle, and spend most of my time as Editor in Chief for Nordic APIs, a niche blog and knowledge center for API practitioners. My writing has also been featured in ProgrammableWeb, Tech Beacon,, and other publications. I also get out into the world to speak occasionally.

He is an experienced writer and editor with deep knowledge of the API space and a knack for helping authors deliver great content on a regular basis. I can only hope to work with him again in the future!"

"I engaged Bill Doerrfeld to perform a technology sprint in the area of emotion recognition. Bill was very thorough in his approach, asking the right kinds of questions to fully understand my needs and expectations. I was very impressed with how Bill was able to gain access and speak to many different leaders in the industry, translate his findings for easy explanations and offer unique perspectives tailored to my wants. He kept me updated on his progress in a timely manner and his output was well written and organized. On top of his work, he was very personable, friendly and a pleasure to work with. I enjoyed working with Bill and learned a lot from him. I hope to have the fortune of working together in the future.!"
