Search Indexing (Search) is an infrastructure team responsible for all data indexing at Meta. Team aggregates data from variety of data sources, denormalize and prepare for building inverted index. - Worked, enriched and rolled out a way to index data without writing any code (configuration driven).

Along the way, created infrastructure around the functionality, so search engineers can properly test, verify their changes before shipping to production.
