Henri is a freelance developer who has turned his interests to a passionate mix of site performance engineering and pinches of user experience.

When not reading the deluge of daily research docs and case studies, or indiscriminately auditing sites in devtools, Henri can be found contributing back to the community, co-programming meetups including the Toronto Web Performance Group, curating performance content for conferences or volunteering his time for lunch and learns at various bootcamps.

Otherwise, he’s focusing on running the fastest 5k possible.

For 25+ yrs, the browser regaled in loading information onto a screen for users. But in 2019, webpage complexities have resulted in resource loading intricacies. With the present day reality in which mobile usage now eclipses desktop, this leaves developers with new found priorities: the disciplined delivery of data. The very forgettable specs of median mobile devices and the fragility of mobile networks leaves us demanding more granular control over resources.

Planet Of The APIs: A Tale Of Performance & User Experience discusses the various APIs (the tested, new and experimental) employed in gaining more of this control over resources, capturing more metrics, and how this can empower developers and other teams in their pursuit of performant mobile #ux.

Five things you’ll learn:

1. Modern APIs: their need and uses
2. Understanding hardware restrictions
3. The challenges of present day resource loading
4. Prioritizing interactivity
5. Auditing with the available tools
