Analyzes 33 million Citi Bike trips loaded into BigQuery (4.5 GB, 33M rows) and visualizes results with Data Studio, Carto and Exploratory. Queries show fleet growth from ~6,000 bikes in 2013 to >10,000 in 2016, subscribers account for ~88% of trips with average trip ~14 minutes vs 35 minutes for casual users, and a single bike ID logs 5,594 trips. Also queries 2.2 TB of GitHub code (≈19 million C# files) and runs NLP on 27k Reddit comments via Cloud Natural Language and JS UDFs (parses in ~16s).
