Messinger was previously Vice President Development at Oracle, where he was responsible for managing the Oracle Coherence, Oracle JRockit, Oracle WebLogic Operations Control, and other web tier products. Prior to joining Oracle, he worked as a venture capitalist at Smartforest Ventures and O’Reilly AlphaTech Ventures.
At Oracle he was responsible, for the development Exalogic, Java SE, FX, ME, and Card, Coherence, Virtual Assembly Builder, Middleware Lifecycle and Applications Lifecycle. Prior to his time as a VC, he founded Gauntlet Systems Corp., which was acquired Borland.
It’s a big development hire for Twitter, as the company says Messinger “was doing web engineering before many used the web.”
In October, Twitter’s VP of engineering Mike Abbott left the company to join Benchmark as an EIR.
