Andy Davies

Web Performance Consultant

Talks

My talks are normally about web performance – why it matters, how we can measure and improve it, browser innovations that are coming etc.

Although I often reuse talk titles I generally update the slides between each talk.

If you'd like me to speak at your event, feel free to get in-touch and we can talk about it in more detail - hello@andydavies.me
