* Lifecycle Management Oversee the endtoend lifecycle of core systems ensuring internal engineering principles are applied from initial build to daytoday operations
* Technical Authority Serve as the primary advisor to the CTOi bridging the gap between platform complexities and executive business goals
* Operational Excellence Lead the continuous improvement of operational resiliency Architect and govern highavailability frameworks including Parallel Sysplex GDPS Geographically Dispersed Parallel Sysplex for IBM Z and PowerHA clusters DB2 Mirror for IBM I
* Proactive Risk Mitigation Proactively identify and mitigate technical risks through deepdive system health checks vulnerability assessments and predictive performance modelling
* Disaster Recovery DR Strategy Design and test robust DR strategies eg Cyber Vault Metro Mirror to ensure nearzero RTORPO for missioncritical workloads
* Incident PostMortems Lead the rootcause analysis RCA for major system incidents implementing architectural changes to prevent recurrence
* 3Strategic Adoption of Open Telemetry OTel
* Standardization Design and implement Open Telemetry collectors and instrumentation patterns specifically tailored for IBM Z and IBM I workloads
* FullStack Integration Enable seamless distributed tracing across hybrid paths from mobile frontends through middleware zCEE CICS MQ to DB2 and back
* Metric Modernization Convert legacy SMF records and system logs into OTelcompliant metrics and traces to provide a unified single pane of glass view
* Performance Engineering Collaborate with DevOps teams to build realtime dashboards that correlate IBM Z and IBM I telemetry with distributed cloud services
* 4Everything as Code Strategy IaC CaC PaC
* Infrastructure as Code IaC Drive the transition to softwaredefined infrastructure using Terraform or zOS Cloud Broker for containerized workload
* Configuration as Code CaC Manage OS parameters and middleware zCEE CICS DB2 MQ via versioncontrolledYAMLJSON files orchestrated through zOSMF and Ansible
* Policy as Code PaC Programmatically enforce security audit and compliance policies eg RACF to ensure automated governance across the hybrid stack
