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.

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.

There’s a short list of people I whole-heartedly recommend for detailed performance work; Harry is right up there at the top.

The CSS architecture I learned from Harry on the NHS project has changed the way I work. Bravo!
