Site-Speed Optimisation – Web Performance and Site Speed Consultant

Audits

Your website is slow. I know why. Web performance is big business for any industry: from recouping lost sales to increasing conversions; reducing running costs to user retention; better SEO to lowering your environmental impact. Let’s work together to identify and fix your blind-spots.
Consultancy

What is your web performance strategy? How much does a 1s slowdown cost you? How do you measure its impact? Is your monitoring effective or even appropriate? How much is web performance worth to your bottom line? Together, we can work out answers to all of those questions and more.
Training

What’s better than one of me? A team of me. Let me show your engineers how to find and fix all of the things that I can. Get your team self-sufficient, equipped with all of the right tools and knowledge to be your own in-house web performance experts. Never run slowly again.

Harry helped our team level up their scalable CSS architecture skills, and to say that he had a large impact on our work is an understatement. We can’t recommend him enough.
Addy Osmani, Google
Harry’s workshop was excellent; we left with tons of new ideas and techniques to improve both the CSS architecture and overall performance of Behance and Adobe Portfolio.
