Excited to be the newest member of the AskTom Team

A little over a year ago Connor McDonald and Chris Saxon took over answering questions posted on AskTom, which covers many topics related to building applications on top of the Oracle Database. Connor and Chris have done an amazing job of keeping up with the constant influx of questions, with nearly 16,000 answered to date.

Last week, I was lucky enough to be invited to join Connor and Chris in answering questions submitted AskTom. So, if you have any burning questions regarding the Oracle Database or building applications on top of the Oracle Database, you can submit them at AskTom and Connor, Chris or I will get back to you!
