The video format allows us to dig deeper into topics we cannot expand on our podcast. In our YouTube channel I am able to share examples, presentations, tutorials and more.


I have had the pleasure of working with David over the last 4 years. I appreciate his willingness to take on scrum master responsibilities in addition to being a developer on that same team at Workday. He is a natural in the scrum master role due to his people skills. As a developer, he was always open to learning new technologies whether it was for a project at work or for his own professional development. His learnings benefitted his team mates, as he was always willing to share his knowledge. I thoroughly enjoy working with him.

I've worked closely with David to create a number of UI components with some complex micro-interactions. He's eager to get it right, he checks his work, and he delivers the functionality as it was spec'd time and again. And he does it with a great attitude.

David was a valuable member of the JStokes team. As our Senior Web Developer, we relied on him to execute everything from landing experiences to digital banners to mobile-first websites. No matter how big or small the project, he met the challenge with positive energy and expertise. He's the kind of guy who is constantly learning new tools, and trying to find better ways of doing things. A true team player and genuinely nice person to work with, David would be an asset to any organization or agency.

David began working within my organization about a year ago. He's a generally self-taught programmer who works tirelessly to succeed. His attitude is outstanding and his commitment to a good solution is great! David is a utility team player and a fine addition to any team. THANKS David!
