Top SchoolBernie Zang is a seasoned engineering leader and founder with over 20 years in product, engineering, and design, currently serving as Director of Engineering at ClassDojo and incubating startups through Zangworks. He combines hands-on front-end and SDK experience—contributing chat and widget features to Cisco’s widely used webex-js-sdk—with a strong track record of shipping marketplace and developer-experience products at Airbnb and Urbandoor. Bernie has repeatedly scaled teams and delivery processes, driving major supply and booking growth at Airbnb and cutting page load times and bugs through technical refactors. He blends product ownership and engineering management, launching tools and internal systems that enabled rapid onboarding of 100k+ listings and operational improvements across organizations. Based in Denver, he pairs technical depth (Master’s in IST, BS in EE) with a practical focus on mentorship, hiring, and building reproducible development workflows. Notably, his background spans both enterprise SDKs and consumer marketplace growth—so he’s equally comfortable architecting developer-facing integrations and shaping product strategy.
