40 years of adventures in software: computer graphics, networking, GUI application development, object-oriented databases, a Java language implementation and now I seem to have settled on graph databases.  I led the storage team at Metaweb. We built freebase.com, the world-writable graph of all common knowledge which became Google's knowledge graph (and also Microsoft's).  In 2014 I moved to LinkedIn to start a next-generation relational graph database project called LIquid:

LIquid has been in production at LinkedIn for several years
