David Van Couvering

David Van Couvering has spent his engineering career crossing the bridge between databases and the middle tier world of application servers, Java and distributed systems. He was the original architect for the Sybase J2EE application server and for the first release of the clustered Sun Java Application Server Enterprise Edition. Currently he is involved in database technology at Sun, working with the Clustra team in Norway, and is a committer to the Apache Derby open source database. He lives in Berkeley and his favorite pasttimes are coding, meditation and spending time with his daughter.
