performance.now() is a single track conference with sixteen world-class speakers covering today’s most important web performance insights. They are selected by our program co-chairs Steve Souders and Tim Kadlec.
Below you'll find our complete line-up. All sessions are geared toward delivering takeaway action items for teams creating fast web experiences across all devices.
Tammy is chief experience officer at SpeedCurve, where she helps companies understand how visitors use their websites, and a cochair of O’Reilly Fluent. Tammy has spent the past two decades studying how people use the web. Since 2009, she’s focused on the intersection between web performance, user experience, and business metrics. Her book, Time Is Money: The Business Value of Web Performance from O’Reilly, is a distillation of much of this research. She also cocurates (with Tim Kadlec) WPO Stats, a collection of performance case studies.
Natasha has been both a web and application developer before becoming Director of Internet Engineering providing expertise on web technologies and internet protocols to the telecoms industry. She attends W3C and IETF working with both standards bodies to support and make recommendations for better user experiences on mobile and across the mobile network.

Katie is a Staff Software Engineer on the Frontend Systems team at Etsy, where she advocates for and implements frontend best practices in collaboration with product engineers and designers. She is passionate about frontend architecture, design systems, style guides, accessibility, frontend performance, and teaching others. Katie recently co-authored the Design Systems Handbook and is participating in the Pastry Box Project, but her proudest accomplishment is creating ohshitgit.com to share her hard-won knowledge of how to get out of your git messes with a bit of humor (and a lot of swears).
There are a lot of books, articles, and online tutorials out there with fantastic advice on how to make your websites performant. It all seems easy in theory, but applying best practices to real-world code is anything but straightforward. Diagnosing and fixing frontend performance issues on a large legacy codebase is like being an archaeologist excavating the remains of a lost civilization. You don’t know what you will find until you start digging!
Pick up your trowels and come along with Etsy’s Frontend Systems team as we become archaeologists digging into frontend performance on our large, legacy mobile codebase. I’ll share real-life lessons you can use to guide your own excavations into legacy code:

Chrome developer tools aficionado (understatement) and Google web performance engineer, will present web performance metrics and measurements in 2018.
Yoav Weiss has been working on mobile web performance for longer than he cares to admit, on the server side as well as in browsers. He now works as part of Google Chrome developer relations team, helping to fix web performance once and for all.
He takes image bloat on the web as a personal insult, which is why he joined the Responsive Images Community Group and implemented the various responsive images features in Blink and WebKit. That was his gateway drug into the wonderfully complex world of browsers and standards.
When he’s not writing code, he’s probably slapping his bass, mowing the lawn in the French countryside, or playing board games with his family.
Loading resources on the Web has always been a performance hurdle. Late discovery, contention and bloat caused it to be the common performance bottleneck. In recent years advances in protocols, browser behaviour and performance APIs improved resource loading significantly, but there’s still room to make it even faster.
In this talk we will go over resource loading improvements browsers have made in recent years, discuss related best practices and describe various innovations that are being worked on to improve resource loading even further.
Andrew is a web developer and principal developer advocate for Fastly, working with developers across the world to help make the web faster, more secure, more reliable and easier to work with. He founded a web consultancy which was ultimately acquired by the Financial Times, led the team that created the FT’s pioneering HTML5 web app, and founded the FT’s Labs division. He is also an elected member of the W3C Technical Architecture Group, a committee of nine people who guide the development of the World Wide Web.
Scott is a designer/developer at Filament Group who lives in sunny Florida, USA. Scott is a tireless advocate of practices that ensure web access for all. He is a frequent presenter at conferences throughout the world and is always chipping away at various open source projects with his colleagues at Filament.

Webpage performance is a high priority for any site of scale today, but it can be easier to build a fast site than it is to maintain one. As a site's features and design evolves, its performance is often threatened for a number of reasons, making it hard to ensure fast, broad access to services. In this session, Scott will consider common conflicts between performance and features such as advertising, personalization, A/B testing, CMSs, and JavaScript frameworks, and share some practices that have helped major sites defend their speed without compromises.
With a client list including Google, Unilever, and the United Nations, Harry is an award-winning Consultant Front-end Architect who helps organisations and teams across the globe to plan, build, and maintain product-scale UIs.
A Google Developer Expert, he writes on the subjects of CSS architecture, performance, and scalability at csswizardry.com, develops and maintains inuitcss, authored CSS Guidelines, and Tweets at @csswizardry.
Like it or not, a huge part of modern web development involves the use of third-party providers: fonts, analytics, ads, tracking, and more all have an impact of performance, and can leave us (or, more worryingly, our visitors) susceptible to performance degradation.
In this talk, we'll take a look at unruly or uninvited (third-)party guests: how to detect them, how to audit them, and how to manage them. We'll also look at the different tools available to help us stress-test and quantify the overhead these third parties bring, and what that means for users and businesses alike.
Michelle is a Software Engineer on the Performance team at Pinterest. She's passionate about performance tooling, working on optimizations, and fighting regressions. When she's not coding, you can find her hiking in the mountains, traveling the world, or planning her next adventure.
Pinterest.com serves millions of requests per day internationally across a myriad of network conditions and devices. This is the story of how the web performance team tackled the task of gathering data, applied a strategic roadmap across the organization, prevented performance regression as developers shipped new features, executed on the best opportunities to improve the Pinterest experience for our users, and made performance a priority for the company.

Perceived performance is not only about fast page loads and delivering the content as early as possible. It is also about all the interactions happening on an already loaded page. Even some of the most popular UI patterns can be a cause of frustration. Understanding what is happening under the browser's hood can help you delight users with a smooth experience and avoid potential performance issues. Let's demystify the rendering process and look into possible optimisations in order to achieve the best experience after the initial page load.
During the talk you will learn: - what the browser rendering process looks like, - which UI patterns can be deadly to the website's performance when mixed with certain user interactions, - how we can help the browser with planning the optimisations ahead.
