Daniel Demmel is a Principal AI Engineer based in London with 11 years of experience building full-stack products and production-grade AI systems. Currently focused on agentic code generation, hybrid front-end/backend agents, and MLOps observability, he blends practical DevEx improvements with security-minded ISO 27001 practices. He has a long history of shipping web and product engineering—from early work in Flash and UX-focused development to leading AI-first transitions at Tangible—and brings strong product instincts from a Product Management certificate and prior Product Owner roles. An advocate of open source, minimalist living and degrowth, he pairs pragmatic engineering with thoughtful values, and balances technical leadership with hands-on coding. Notably, he experiments with non-chat LLM UX patterns and machine-readable knowledge bases to move LLM integrations beyond simple conversational interfaces.
