JavaScript experts, mentors, speakers

I'm a freelance software engineer, former CTO and lifelong teacher. Back in 2010 I wrote neural networks from scratch in Java to model parts of the brain. These days I build mobile and web apps with AI agents and teach technical as well as non-technical teams about AI and software development. For years I also taught React and React Native, but now I outsource these skills to agents. For the past year I've shared thoughts about the AI shift on LinkedIn. On stage, I try to make complex things feel fun, interactive and a bit human.
