Shem Magnezi

Career

Software engineer, mentor, writer and international speaker with more than 20 years of experience across startups and public companies, from first employee to co-founder and CTO. I work heavily with AI: helping teams adopt it, accelerating the work of every department, and building tools, products and agents with it. I help people understand both the business context and the underlying architecture. A generalist at heart who just loves solving users’ problems.
