What I'm looking for

I am seeking senior mainframe roles where I can apply COBOL/DB2/CICS expertise, lead complex integrations, improve performance, and contribute to reliable, automated enterprise systems within collaborative teams.

I am a Senior Mainframe Developer with around 9+ years of experience designing, developing, testing, and supporting large-scale enterprise applications on IBM mainframes, specializing in COBOL, JCL, CICS, DB2 and UNIX.

I have led development and production-support efforts across healthcare (Medicaid/Medicare), finance, telecommunications and automotive domains, authored HLD/TSD artefacts, implemented DB2 stored procedures, optimized SQL/DB2 performance, and converted COBOL workloads to Java Spring Batch where required.

I am experienced with mainframe tools (Expeditor, Endeavor, ChangeMan, File-Aid, INTERTEST), middleware integration (Apache Camel, MQSeries, SOAP/RMI), automation of batch processes, and cross-location coordination to deliver reliable, scalable solutions with strong attention to quality and SLA adherence.
