Hybrid Cloud & Platform Modernization

· Support UNIX workloads running on VMware (vSphere/vSAN/vXrail) and prepare platforms for future cloud integration.

· Assist with cloud-readiness assessments, infrastructure modernization efforts, and immutable infrastructure adoption.

· Collaborate with Cloud, DevOps, and Cybersecurity teams on secure hybrid operating models.

Documentation & Governance

· Maintain robust documentation in Confluence: HLD, LLD, SOPs, DR plans, build guides, access policies, GitHub repositories, and architectural decisions.

· Ensure all platforms and automation meet compliance standards (CIS, FFIEC, SOX, ISO
