In short, I am database engineer with 20 year’s DB2 DBA experience.
I started IT career as COBOL programmer about 40 years ago.
Next, I changed my career to support engineer for ISV database software.
I supported CA-DATACOM and CA-IDMS for 8 years.
From 1999, I became infra engineer of IBM mainframe. My specialty is DB2 for z/OS.
