  • Enabled the launch of 30 new product categories in multiple countries into Amazon's catalog by collaborating with the business teams to develop appropriate product validation logic and implementing matching criteria
  • Designed and implemented a tool used daily by hundreds of seller support agents to correct mismatched seller product listings in the catalog. Drove down related merchant contacts by 43% and reduced the time to resolve such issues into a few mouse clicks
  • Built tools for auditors to measure quality of catalog impacting decisions made by the item authority's product matching algorithms, leading to insights and policy changes that reduced duplicate creation for non‐Novelty items by an estimated 58% in the US
  • Developed the Herd distributed workflow platform and drove changes to enable multi-tenancy and safe client isolation allowing us to triple the number of clients on the platform within the timescale of months without sacrificing availability
