Henri Helvetica

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.

DEADScript is a presentation highlighting the resources we’re loading in modern development, and JavaScript’s unique role in this disquieting environmental dilemma.
