    • Plan and execute MQ upgrades (e.g., WMQ V7.0.1 V7.1.0).
    • Design and implement MQ health‑check tools (Rexx, CLIST).
    • Integrate MQ with automation tools such as CA‑OPS/MVS and SA z/OS.
    • Configure MQ security using RACF, ACF2, or Top Secret.
  • Mainframe Systems Programming (z/OS)
    • Install, customize, and upgrade z/OS and related subsystems.
    • Perform SMP/E maintenance, rebuild SMP environments, and manage toleration maintenance.
    • Configure and support CICS, IMS, VTAM, TCP/IP, and other core subsystems.
    • Manage DASD, tape systems, DFSMS, DFSMShsm, and storage utilities.
  • Security & Compliance
    • Review and enhance RACF/ACF2/TSS profiles.
    • Implement mainframe security frameworks for regulated industries (banking, insurance).
    • Conduct audits and produce security reports for compliance (OCC, regulatory bodies).
  • Automation & Monitoring
    • Implement and customize automation environments (SA z/OS, CA‑OPS/MVS).
    • Install and configure monitoring tools (OMEGAMON, TMON, MainView).
    • Develop automation exits and scripts to improve system reliability.
  • Programming & Tooling
    • Develop Rexx, Assembler, CLIST, PL/I, COBOL utilities for system automation and reporting.
    • Create JCL for backups, migrations, and maintenance tasks.
    • Build custom tools for performance tuning, forecasting, and operational reporting.
  • Client Support & Delivery
    • Work directly with enterprise clients (banking, telecom, insurance).
    • Provide technical leadership, knowledge transfer, and hands‑on demos.
    • Support multi‑national environments with high‑volume transaction workloads.
