Having spoken at well over 50 public events, sharing my knowledge with development and product teams is something I am both very experienced with and hugely passionate about. If you’re running an event would like me to speak, I have prepared some information for you.

As well as speaking at development conferences, I can (and indeed do) speak at private engagements for companies and their staff. If you are a company who would like a tech talk to be delivered on-site to a private audience, please do get in touch.

If you feel like you’d like something a little more involved and in-depth, then you’re probably looking for a workshop. I’ve run countless workshops for both public events and private clients. Read more about what that involves.

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.
  • How long does the talk need to be? Do you have a set talk duration? 45 minutes is usually ideal.
  • Do you have any specific AV limitations? I prefer to use headset or lapel microphone, and would definitely rather use my own laptop to present from.
  • Do you cover speaker expenses? Flights, hotels, train journeys, etc.
  • 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.
  • When can I start publicising your event? Do you want to keep the lineup quiet for a while, or can I add your event to my speaking list immediately?
  • 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.

What’s in It for You?

I will help to promote and publicise your event. I will endeavour to make myself available to attendees for the entire duration of the event. I will attend all social activities surrounding the event. I will deliver a quality talk of practical relevance. I will gladly allow you to record and distribute my talk. I hold myself to a high standard.

Sound okay? Get in touch!
