Deep JavaScript & AI talks from engineers building real systems in a 3 days event
This looks like a pretty strong, developer-focused AI conference with a clear theme: AI + modern frontend/backend engineering + security + agentic systems. It’s not a generic “AI hype” event — it’s very builder-oriented.
3 Days of talks, workshops, & real world case studies
Practical lessons on performance, scaling & modern JS Architecture
Learn directly from senior engineers, creators and industry leaders
Network with senior frontend & Node.js developers from around the world
