I provide CSS and performance consultancy to companies of all sizes across the globe. From advice on how to work better as a team, to how to scale a large codebase; how to rationalise the design process, to how to write better quality responsive User Interfaces.
I work on products and long-running projects, focusing on scalability, maintainability, performance, and more. I usually join product teams for short, initial kick-off sprints in order to set up architectures and workflows, and to leave teams self sufficient after I’ve left.
I run workshops and training sessions for existing teams, getting them up to scratch and prepared for writing and managing front-ends that they expect to grow. Performance concerns, workflows, design process, and more, tailored to your company, products, and team.
Harry gave the team a strong footing for identifying performance issues on iPlayer. With his knowledge, we were able to roll out quick fixes to our audiences without the need for big rewrites, all within just two days.

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!
