Justin Miller is a versatile freelance developer, consultant, and maker with over 25 years of internet-era technical experience and 17 years of focused professional practice, currently based in Portland, Oregon. He led mobile engineering at Mapbox as an early hire—shaping cross-platform mobile tooling and open-source contributions to projects like mapbox-gl and TileMill—then transitioned to hardware prototyping, embedded firmware, and product design. Equally at home in low-level firmware and high-level UI, he blends systems administration, iOS/macOS development, and OpenGL-backed mapping work with practical devops and founding experience. A digital artist and conference photographer, he exhibits interactive installations and runs a commercial photography business, bringing a maker’s aesthetic to product and hardware design. He advises startups as an angel investor and consultant, helping teams on hiring, technical stacks, and market strategy. Known as a patient mentor and engaging public speaker, he pairs technical depth with the ability to communicate clearly to executives, engineers, and customers.
