Mark Grover is a product manager at Lyft, working on data projects and is a founder of the open-source data discovery platform Amundsen. The company has grown significantly over the years, resulting in an increasing amount of data that needs to be processed and analyzed to provide better experiences for riders and drivers. However, this growth has also led to issues with data trust and discovery, as users may not know if a particular dataset exists or is still being populated. Grover and his team at Lyft set out to solve this problem by building Amundsen, an open-source platform that uses metadata to provide a searchable interface for discovering and accessing trusted datasets. The platform has been adopted widely within the company, with over 200 scientists using it every week, and has seen significant improvements in productivity. Grover also discusses the future of Amundsen, including its potential use in other applications such as compliance and ETL, and how it aims to provide a personalized experience for users, showcasing their experience and relevant information to improve trust and reduce manual curation.
