As the leader of the Big Data Team, my accomplishments cover three core components:• Led the definition, development and adoption of the Nokia Big Data Analytics platform, a petabyte-scale platform, combining NoSQL and Hadoop (using CDH) with SQL aggregation engines and tools, running in Nokia data centers.

Responsible for the definition and development of data governance around that Big Data asset, including data glossary, master data management, privacy/security/retention/quality policies. Built the data asset to multiple petabytes, with 10s of terabytes ingested weekly, and 10s of terabytes produced via analytical processes.• Built a team of data scientists that delivered clear insights to address the company's pressing business opportunities using analytics. Focused in the area of 'location analytics', building place recommendation models and rich place profiles for use in varied applications.
