Speaking and Workshops

I speak about—and run workshops covering—big CSS, its architecture, and writing it in large teams on large products in a performant manner that scales. If you would like me to speak or run a workshop at one of your events, please read my speaker’s questions before getting in touch.

I also run private workshops, where I come into your offices and get hacking with your team. If you would like to organise one of these then fire me an email.

Request to Speak

I would absolutely love to speak at your conference! However, I do just have a few questions to make the whole process a lot simpler and upfront for everyone involved. If you could fire me an email answering as many of the below as possible, I’d be really grateful. If you don’t have answers to everything just yet, please don’t worry—this is just a rough starting point, not a test. Please also remember that there is no right or wrong answer to any of these questions.

  • When and where is your conference? I once travelled 12,000 miles to give a talk; I’m not afraid of a commute.
  • How many attendees do you expect to have? Rough figures or previous sizes are perfectly fine.
  • What kind of audience do you have? It helps to know what the audience will be like (e.g. mainly front-end developers, mainly designers, etc.).
  • Which other speakers have you approached? It helps to be aware of any other speakers who run the risk of delivering similar talks.
  • Do you cover speaker expenses? Flights, hotels, train journeys, etc.
  • Do you provide a plus-one ticket? Is there a chance to bring someone along who might also be interested in attending?
  • What kind of talk would you like? I usually give technical talks (CSS architecture, performance, etc.), but am open to discussing other topics.
  • Do you require a brand new talk? Writing talks takes a lot of time and effort: forewarned is forearmed.
  • Do you plan to compensate speakers? I usually charge a fee to speak, however its value is open to discussion for indie and non-profit events.

Sound okay? Get in touch!
