The web should work for everyone.

I help organizations who want to make sure it does.

I help companies improve the effectiveness of their sites by ensuring that they perform quickly (no matter the device or network) and are accessible to all.

Just as importantly, I help arm companies with the tools, knowledge and processes they need to be able to ensure their sites remain that way for the long-haul.

Training is a great way to kickstart your efforts. I offer a variety of training specifically tailored to the needs of your team to make sure you're armed with the knowledge you need to create fast, inclusive and future-friendly sites.


A clear roadmap is an important first step in building a site that will perform well across a myrid of devices, networks and contexts. Detailed auditing and analysis will help you to develop and impactful and efficient plan of attack. You'll be armed with a clear target and a map of how to get there.

Time to roll-up our sleeves. I can work with you from the early planning stages through the actual development of your site, providing help along the way to make sure you're left with a high-quality and impactful site.

Tim did a masterful job of combining the "why" for performance, with technical details on browsers and underlying internet technologies. He skillfully summarized that information into practical tips we were able to implement immediately while we plan larger projects to improve performance. Steve Dalonzo, Software Engineer, Priceline
