Sam Jeffs is a transit-focused developer and community builder with six years of hands-on experience designing user-facing tools and realtime transit systems in the Bay Area. Currently a Student Assistant for Transportation Solutions at SJSU and a board member at Catenary, he blends front-end engineering—demonstrated by UI work on the Electron-based Cider music client—with operational integrations like Cloudflare Workers that process thousands of transit alerts daily. He has scaled community engagement (growing a transit Discord to 1,200+ users in a weekend) while maintaining data hygiene across dozens of agencies as Catenary’s former Communications Manager. A self-taught programmer and amateur photographer, Sam applies visual and technical sensibilities to create accessible web and mobile experiences for local organizations. He’s motivated by learning-by-doing and leverages open-source contributions and volunteer work to iterate quickly on real-world transit problems. Based in Half Moon Bay, he combines civic-minded product work with a knack for turning messy public data into reliable, user-centric services.
