Why It Matters

Creating a website is not just about making something fast and pushing it to the web; it's about crafting an experience for your users.

Sites that answer questions, let users find what want and get it, fast and easily. These are the experiences that users will return for over and over, and share with their friends.

I apply web performance best practices and optimization techniques to improve every stage of the user experience. I can work with your team to make sure performance problems don't return.

Whether I'm fine-tuning Core Web Vitals, reducing JavaScript payloads, automating performance monitoring, or mentoring teams on best practices, my goal is the same: make the web better.


How I Work

In today's competitive digital landscape, performance isn't a luxury, it's essential. Faster pages improve SEO, boost engagement, reduce bounce rates and create conversions.

I help teams balance business needs with technical excellence by optimizing critical metrics like LCP, CLS, and INP, and implementing scalable solutions that stand the test of time.

My approach is grounded in real data and provides real results:

  • Performance Audits & Strategy

    Identify bottlenecks and build prioritized plans for improvement.

    I helped reduce Estee Lauder's global average LCP from 3.26s to 1.78s and CLS from 0.41 to less than 0.10.

  • Monitoring & Automation

    Daily reports and instant alerts ensure metric increases are immediately noticed and actionable.

    I set up CI/CD tests and synthetic monitoring to catch regressions before they affect users and real-user monitoring to catch anything that sneaks through.

  • Front-End Optimization

    Performance is a game of milliseconds and bytes; the less you send, the faster your user sees it.

    I continuously fine-tuning HTML, CSS, JavaScript, media assets, caching, CDN strategies, and more to ensure the lightest payloads possible.

  • Collaboration & Advocacy

    The modern web is an absolute team effort. Getting everyone involved, educated and taking ownership is paramount.

    I work closely with designers, developers, product owners, and leadership to integrate performance into every stage of development.


What I've Done

I've led performance initiatives for major enterprise sites, including monitoring and optimizing 250+ e-commerce sites across 20+ global brands; I've helped small agencies, evaluating and improving their entire customer catalog with scalable initiatives; I have also helped small businesses cut corners and shave excess baggage to improve their user experience.

My work has significantly cut load times and improved Core Web Vitals at scale, ensuring fast, reliable experiences for real users world-wide.

Let's create something exceptional for you and your users.
