As a data team leader, Jess has always been very attentive to mapping out the core data that the team needed to serve, and has always prioritized building this foundation with high data quality, clear modeling, and best practices, rather than getting stuck in a common loop in data teams: meeting the most urgent demand and always getting stuck in the same vicious cycle. During the time we worked together, Jess has always paid close attention to governance programs and ensuring that her data was following best practices. She has also always been very careful to ensure predictability for her team and stakeholders about what would be possible deliverables.
