Henri is a developer who has turned his interests to a passionate mix of site performance engineering with pinches of user experience. That, combined with his leadership of the Toronto Web Performance meetup, JAMstack Toronto meetup and curating conference content, has led to COMMAND-H — a small org in support of all his passions: people and developers. When not reading the deluge of daily research docs and case studies, streaming, or profiling sites in his favourite tool, Henri is focusing on running the fastest 5k possible (surprise surprise), encouraging a healthy lifestyle and sharing it all via #devsWhoRun.

But just as the web changed, so did users of the web AND their needs. Performance engineers have monitored the lavish and liberal use of frameworks, resulting in the disservice to users AND their user experiences. "R3ACT" is talk that will uncover and discuss some performance perils as they appear on the web, with React in mind, supported by lab and rum data.

In 2023, we have begun to pay more attention to metric tonnes. DEADScript is a presentation highlighting the resources we’re loading in modern development, and JavaScript’s unique role in this disquieting environmental dilemma.
