Gil Zilberfeld

Gil Zilberfeld has been a software practitioner since the days of his Sinclair ZX81. With over 25 years of hands-on experience, he is a consultant, trainer, and speaker who helps development teams elevate their craft. Gil challenges conventional thinking about how software gets built - whether that's outdated QA dogma or the assumption that AI coding agents will just figure out your engineering practices on their own. He builds real systems with AI tools daily, and shares the honest lessons: what works, what breaks, and what needs mechanical enforcement no matter how smart the model gets. From TDD and clean architecture to AI-assisted development workflows, he provides actionable frameworks grounded in real production experience.
