Services
Specialist IBM mainframe consulting — from CICS and z/OS to RACF security and training. Built on 40+ years of real-world experience, delivered personally by Anji Stephens.
CICS Consulting
From someone who helped restructure CICS at IBM Hursley. I bring a development-level understanding of how CICS actually works under the hood — not just operational knowledge. Whether you’re tuning performance, planning a migration, or modernising legacy transactions, I’ve done it across the world’s most demanding financial institutions.
- CICS performance analysis and tuning
- CICS TS migration and upgrade planning
- Transaction routing and workload management
- CICSPlex SM implementation and optimisation
- Application modernisation and API enablement
- Troubleshooting and incident resolution
Mainframe Security & RACF
Security on the mainframe starts with getting access control right. I specialise in RACF implementation, auditing, and hardening — helping organisations ensure their z/OS environments meet the most rigorous compliance and security standards. From initial assessments to ongoing security posture management, I protect the systems that matter most.
- RACF security audits and health checks
- Access control policy design and implementation
- Security compliance reviews (PCI-DSS, SOX, GDPR)
- Privileged access management on z/OS
- Security incident investigation and remediation
- Digital certificate and encryption configuration
z/OS Systems Programming
z/OS is the foundation everything else runs on. I provide specialist systems programming consulting for organisations that need deep platform expertise — from IPL and SMP/E management to performance tuning, automation, and middleware integration.
- z/OS system administration and configuration
- SMP/E and maintenance management
- Performance tuning and capacity planning
- JES2/JES3 and workload management
- Middleware integration (CICS, MQ, DB2)
- Migration and upgrade planning
Security Audits & Training
Technology is only as strong as the people who manage it. I deliver security audits that identify real vulnerabilities, and tailored training programmes that build your team’s capability to maintain security after I leave. Every engagement includes knowledge transfer as standard.
- Comprehensive mainframe security audits
- RACF administration training courses
- CICS fundamentals and advanced workshops
- z/OS security best practices training
- Customised workshops for your technology stack
- On-site and remote delivery worldwide
Direct Access
No account managers or project coordinators. You work directly with me from the first call to the final deliverable.
Flexible Delivery
On-site or remote, short-term assessments or longer engagements. I fit the format to your needs, not the other way around.
Knowledge Transfer
Every engagement includes documentation and team upskilling. The goal is to build your internal capability, not create dependency.
