Born just north of Pittsburgh, Pennsylvania, my family moved to Waianae, Hawaii just after I completed seventh grade. I moved to San Francisco, California when I turned 21, spent four years near Washington, DC, a little over six years in New York City, the next 11 years in Hohenecken, Germany, and since July of 2023 in Oroville, California.
My web career began in 1998 with a confluence of happenstance and necessity: Just hired to manage a small hotel in San Francisco, I asked about their website and was told that a friend was working on it, but was taking longer than expected. So I bought a book (Elizabeth Castro's HTML5), dove in, and never looked back.
The book is still on my shelf, but doesn’t get used much anymore. I quickly stretched to CSS and JS, then shortly into ASP and MS SQL Server, before discovering WordPress, which got me into PHP and MySQL.
I now specialize in web performance. Everything from tightening your TTFB to helping get your LCP onscreen faster to stabilizing your CLS and helping your users get a faster INP.
When not noodling with code, I can usually be found hiking, biking, gardening, traveling, reading and/or just hanging-out and enjoying life with my wife, friends and family.

Fast by Design: A Masterclass in High-Performance Web Engineering
Attending this masterclass, you will be able to architect, monitor, and troubleshoot complex web performance regressions using a combination of deep-dive manual diagnostics and AI-assisted workflows. It moves beyond high-level theory to provide a technical roadmap for engineering resilient, high-speed digital experiences in high-stakes environments.
We kick off with a level-setting session to ensure everyone is aligned on the core metrics that define the modern user experience, including the foundational principles and nuances of Core Web Vitals.
Moving into active diagnostics, we will examine live production performance issues found on major corporate websites to see how bottlenecks manifest in the real world. You will learn to navigate the complex landscape of monitoring by comparing Real User Monitoring (RUM), Synthetic testing, and APM. We will demonstrate how combining these tools with CI/CD regression tests builds a robust observability strategy that catches issues before they impact your bottom line.
We will also focus on the evolving role and impact of Artificial Intelligence in performance engineering, including DevTools MCP to automate trace analysis, leveraging LLMs to refactor rendering-heavy JavaScript and redundant CSS.
The day will also feature a hands-on "performance gauntlet" where you will apply these techniques to debug and resolve real issues in a live codebase, so bring your laptop.
This masterclass is designed for web professionals who want to move beyond automated scores and master the art of modern performance engineering.
