Nimble

Fast does not mean simple. By understanding how the web works, we use technology to do the heavy lifting accomplishing more with less, sacrificing nothing in the process.

Speed is not longer an exception, it’s the rule to be viable and compete. We are obsessed with building tools that load, respond and interact super fast. Welcome to the millisecond age.

Every web-based project is guaranteed to earn at least a 96/100 ranking in Google PageSpeed recommendation metric. The average online is 72/100, atduo.com is 100/100.

We follow every Yahoo’s YSlow recommendation with A+ ranking for 99% of our projects.

The top 5%

Slow means deficient to the eyes of your visitor. Speed is not a product of chance. Projects that matter pay attention to loading speeds and speed is in our mind from design through deployment. That’s why our websites load faster than 95% of all sites published online.

Mackenzie

For the last 17 years, I wake up every day and look forward going to work doing what I love: my passion, art, and my craft, coding. As a full-stack developer with degrees in marketing and Computer Science, I have founded several startups and work as the CEO and lead developer for DUO. I grew up in 5 countries and speak 3 languages.

I have a passion for helping others explore and pursue the full potential of their idea or their business. In pursuing that passion I’ve co-founded several tech startups and work as COO for DUO. I have four degrees, 3 undergrad degrees from New England and my MBA from Syracuse. I’ve lived in Asia for 3 years working with Hyundai Group and the Brazilian Embassy of South Korea resulting in the establishment of new business and new job creation in Brazil. I value giving a hand up and volunteer for a number of causes.
