I'm currently the architect of WebSphere Application Server enterprise connectivity (think JDBC, JCA, etc) and for WAS on the IBM i platform. I've enjoyed the last 13-ish years working on WAS and in particular the past few years working on Liberty has been fun. Prior to architecting for IBM, I worked for a cool start-up on wireless app dev when mobile connectivity was still in it's infancy. Prior to that, I rode the telecom bubble working on hardware, firmware and software during the phone network digitalization revolution. When I'm not typing, I'm mountain biking in one of the many mountains or canyons of New Mexico.

Use connection validation to check that pooled connections are still valid before using them, and connection initialization to run SQL commands when connections are created.
