I have more than 30 years experience in all aspects of SDLC of primarily high volume processing. Much time was spent of interfaces and data conversions of old systems to new platforms and creating online query systems into legacy IMS databases. I have expert knowledge of IMS DC/DB and application related DBMS issues, e.g. PSB and DBD design and all aspects of Hogan application development. I enjoy application development and design of efficient systems both online and batch.
