Jeff Griffiths
Product Consultant at Self-employed
Vancouver, British Columbia, Canada
Summary
👤
SeniorJeff Griffiths is a product-focused technologist with 16 years of experience translating deep engineering problems into developer-first tools and experiences. He led developer tooling and core browser product teams at Mozilla, shipping Firefox Developer Edition and pioneering CSS Flex/Grid tooling that drove a 400% increase in active users and dramatically improved stability and performance through multi-process architecture. At Fission he steered product and team growth around distributed identity and data ownership, and at AWS worked on serverless developer experiences—demonstrating a pattern of tackling platform-scale developer problems. Now a product consultant and advisor, he combines hands-on engineering fluency (including contributions to Mozilla’s Add-on SDK) with user research and business strategy to build products people genuinely rely on. Jeff is comfortable sketching architecture one moment and running user tests the next, and he’s known for finding the developer-facing feature no one asked for until they can’t live without it. Based in Vancouver, he pairs pragmatic technical depth with curiosity about emerging web primitives and LLM-driven media experiences.
