About

I'm an IT Infrastructure & Cloud Services Manager specialising in Data Center Transformation, Hybrid Cloud Architecture, and large-scale Migration & Modernisation across AWS, Azure, and GCP. At Accenture, I've led end-to-end infrastructure programmes for global enterprises . — delivering complex, mission-critical transformations on time, at scale, and with zero data loss. What I bring: ▸ 17+ years of deep hands-on expertise across IBM AIX, RHEL/SUSE Linux, Solaris, Windows Server, and VMware vSphere — from build to production to decommission ▸ Cloud architecture and migration execution across AWS, Azure, and GCP — roadmap design, risk analysis, capacity planning, and cutover delivery ▸ High availability engineering: PowerHA, Pacemaker, VMware HA/DRS, GPFS — because downtime is never acceptable ▸ Infrastructure automation at scale using Ansible, Terraform, and PowerShell — turning manual operations into repeatable, auditable pipelines ▸ Security & compliance: CIS benchmarks, RBAC, MFA, IAM — across multi-OS and multi-cloud environments ▸ Cross-functional leadership: mentored 20+ engineers, defined SOPs, and drove ITIL-aligned delivery across global accounts I bridge the gap between deep technical execution and strategic business outcomes — translating complex infrastructure challenges into solutions that are secure, scalable, and built to last. Currently open to senior Infrastructure Management, Cloud Architecture, or Managed Services leadership roles where scale and reliability are non-negotiable. 📩 [email protected] | 📍 Kolkata, India · Open to remote,relocate & global opportunities.
