Since the inception of the Elasticsearch project I have built production systems covering every feature of the engine ranging from full text and metadata searching to pure large scale analytics. My experience includes deep dives into linguistics for many languages making sure key features of each language is treated with respect. I understand how to balance relevancy and recall, and to build top tier search features such as Query Understanding.
Big data sql
- 3 years experience
Leveraging SQL skills in big-data engines that use the power of SQL over Hadoop, or stand-alone engines such as PrestoDB and U-SQL with Azure Data lake. I can harness any scale of data across a variety of platforms. Covering ingestion, ETL, calculation layers and more. My SQL experience goes even further back to the 90's covering every major database that has existed.
