About the author

Hi, my name is Dennis! As a freelancer and consultant, I work with tech organizations worldwide to help them build effective, high-quality software. It's my mission to help these companies get their idea off the ground quickly and in the right way for the long haul.

For over 20 years, I've worked with startups and other tech companies across the globe to help them successfully build effective, high-quality software. My experience comes from working with early-stage companies in New York City, San Francisco, Tokyo, and remotely with dozens of organizations around the world.

My main areas of focus are full-stack web development, test automation, and DevOps. I love sharing my thoughts and expertise around test automation on my blog, Dev Tester, and have written a book on the same topic.
