Mitchell enhanced the smarty/changelog repository by delivering updates to the International Street API and US Enrichment property responses. The work focused on adding occupant use data and financial history, enriching the data available for risk assessment and customer insights. Mitchell approached the task through careful API development and thorough documentation, ensuring the new features integrated smoothly with the existing JavaScript SDK. The enhancements were released as part of JS SDK version 7.4.0, demonstrating proficiency in API design and data enrichment. While no bugs were fixed during this period, the work provided deeper, more reliable data for downstream applications and users.
