I help organizations improve the effectiveness and reach of their sites by ensuring that they perform quickly—and stay that way.

There's no faster way to sabotage your businesses growth and undermine the effectiveness of your site than to build a site with poor web performance. Slow-loading sites:

  • repel potential customers
  • increase bounce rates
  • limit overall reach
  • reduce conversion rates

I help ensure that doesn't happen to you by helping you make your site fast, and arming you with the knowledge, tooling and processes you need to establish a lasting culture of performance in your organization.

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

About Me

I'm an independent web performance consultant focused on building a web everyone can use.

I wrote High Performance Images (O'Reilly, 2016) and Implementing Responsive Design: Building sites for an anywhere, everywhere web (New Riders, 2012). I was also a contributing author for Smashing Book #4: New Perspectives on Web Design (Smashing Magazine, 2013) and the Web Performance Daybook Volume 2 (O'Reilly, 2012). I host Chasing Waterfalls, a podcast featuring conversations with the people working to make the web faster for everyone, and am co-chair for performance.now(), the web performance conference for web professionals.
