Experience
Fixing the Amazon.com Product Catalog
https://patents.google.com/patent/US20150378975A1/enI designed and coded several components of the larger pipeline my team was powering. More importantly, I developed a new algorithm for phrase extraction, and scaled it to handle thousands of categories, and billions of products across several marketplaces. EMR (Hadoop, Spark), S3, and several other AWS offerings were integral to the overall architecture, and are now essential elements of my design toolkit.
Knowing that my work had a significant positive impact on several downstream systems (recommendation, search, browse) was a great motivation, but the technical challenge was a driver too. Reprocessing a very large collection of text documents daily, and cost-effectively is not a trivial task. Applying machine-learning at that scale also comes with fun challenges.
