I have 8 years of experience in Mainframes(4-Investment banking domain, 4- transportation domain) and I worked in DB2,IMS/DB, JCL, CICS, COBOL last year.
I am looking for a career growth. My interests are technically oriented and I would love to help develop products.
I am not interested in becoming a Project Lead / Manager.
What should I do that will make me more valuable in the market and increase my knowledge or scope?
