Rockstar🎓
Top SchoolDaniel Walmsley is a founder and CTO with 15 years of engineering and leadership experience building AI-driven products and large-scale web platforms. Recently leading AI efforts at Automattic, he designed and shipped customer support chatbots, model evaluation frameworks, and the Big Sky Agents open-source SDK while integrating transformer and diffusion models into WordPress products. Comfortable as both IC and tech lead, he has deep full-stack chops—from backend PHP contributions to Jetpack and AMP integrations to front-end work on the WordPress.com Calypso UI—and a track record of shipping pragmatic, production-ready systems. Now building Gravity Rail, he focuses on trusted AI orchestration for complex teams and processes in demanding environments. A long-time open-source contributor, he balances engineering rigor with product sensitivity, and—less obvious—brings a creative background in theatre and media that informs his user-centered approach.
