From frontend developer to full-stack lead early in my career to co-founder at ImageKit, web performance has been central to everything I have done. I worked on the first version of the code at ImageKit that now serves billions of media requests every day. These days, I spend less time coding and more time sharing with devs how to optimize images and video delivery on the web. Delighted to get a chance to speak with the ZurichJS developer community - thanks to a chance crepe encounter with Faris at CityJS London!

Video optimization for the web: The Missing Piece in Lighthouse
Video is everywhere on the web, from hero banners to product videos to full-blown streaming. However, while Lighthouse reports issues related to images, scripts, and more, it doesn't really address video performance. That means streaming can suffer for end users, resulting in buffering and slow starts, while businesses incur huge data transfer costs due to unoptimized delivery. In this talk, we'll explore some quick wins every developer should know: optimizing videos size and format, optimizing streaming for every device and network, and different video loading strategies to improve performance. In just seven minutes, you'll leave with a toolkit to make your videos load faster, play smoother, and feel as polished as the rest of your app, closing a significant gap that performance audits often overlook.
