Devesh Tailor

Administering a multi-platform server infrastructure of Windows Server and Linux (RHEL/Ubuntu) environments, with a focus on reliability, security, and scalability aligned to data center standards. Key responsibilities & achievements: • Deploy, configure, and maintain physical and virtual servers (VMware vSphere/ESXi, Hyper-V) across production, staging, and DR environments • Manage core network services — Active Directory (GPO, OU management), DNS zones, DHCP scopes — ensuring zero-downtime directory operations • Execute OS patching, firmware updates, and security hardening per CIS benchmarks; track compliance through Qualys vulnerability assessments • Manage SAN/NAS storage allocation, LUN provisioning, and backup jobs; maintain and test disaster recovery runbooks • Automate repetitive infrastructure tasks using PowerShell scripts — reducing manual intervention by ~30% • Monitor server health, resource utilization, and alerting thresholds using SNMP-based tools; proactively resolve performance bottlenecks before SLA breaches • Handle Incident, Change, and Problem tickets in ServiceNow, consistently meeting P1/P2 response SLAs • Support Workspace ONE (UEM) deployments for enterprise endpoint lifecycle management vSphere/ESXi DR environments CIS benchmarks LUN provisioning PowerShell automation SNMP P1/P2 SLA

Worked in partnership with Schneider Electric — a global leader in data center power, cooling, and physical infrastructure — supporting enterprise clients in deploying and maintaining mission-critical IT environments. • Assisted in the assessment and configuration of data center physical infrastructure components including power distribution units (PDUs), UPS systems, and cooling/thermal management solutions • Supported clients in rack layout planning, structured cabling standards, and equipment deployment aligned to Schneider EcoStruxure and DCIM frameworks • Collaborated with technical teams to ensure server environments met uptime, power efficiency (PUE), and redundancy requirements • Provided on-site and remote technical assistance for infrastructure health checks, preventive maintenance scheduling, and hardware lifecycle management • Gained direct exposure to hyperscale and enterprise data center design principles — power capacity planning, N+1 redundancy, hot/cold aisle containment

Delivered L2/L3 infrastructure support for enterprise clients within a large-scale managed services environment — operating at the process discipline and SLA rigor expected in data center and hyperscale operations. Key responsibilities & achievements: • Provided advanced troubleshooting and resolution for Windows Server and Linux systems, reducing mean time to resolution (MTTR) on critical incidents • Managed and optimized Active Directory environments — user/group provisioning, GPO tuning, trust relationships — across multi-domain enterprise setups • Collaborated with cross-functional teams (network, storage, security) on infrastructure change management and root-cause analysis • Ensured adherence to ITIL-based incident, change, and problem management processes via ServiceNow • Supported server migrations and OS upgrade projects with minimal production downtime • Maintained documentation for runbooks, SOPs, and configuration baselines — critical for audit trails in regulated data center environments • Gained exposure to security compliance workflows: vulnerability scanning, patch compliance reporting, and access control audits

Delivered L1/L2 IT support and infrastructure operations within a large-scale BPO/managed services environment, maintaining service continuity for enterprise clients across time zones. • Handled end-user and server-side incident resolution, maintaining adherence to ITIL-based SLA targets across Incident and Request Management workflows • Supported Windows server environments — user account management, AD administration, basic GPO troubleshooting, and access provisioning • Performed routine system health checks, log monitoring, and ticket escalation for critical infrastructure issues • Contributed to standardized processes for onboarding, offboarding, and access management in compliance with enterprise security policies • Operated within a high-volume, 24/7 shift environment — building the operational discipline essential for data center NOC roles

Managed Windows and Linux server environments for enterprise clients, focusing on system stability, security, and responsive infrastructure support. • Administered Active Directory — user/group management, OU structure, and GPO configuration for enterprise client environments • Handled DNS and DHCP server management, ensuring reliable name resolution and IP address allocation across the network • Performed server monitoring, log analysis, and first-response troubleshooting for hardware and OS-level issues • Executed patch management cycles and antivirus/endpoint security compliance checks • Supported server build activities: OS installation, post-build configuration, and handover to production

Entry-level server engineering role where foundational skills in server hardware, operating systems, and enterprise network services were built in a hands-on production environment. • Assisted in deployment and configuration of physical servers — rack installation, cabling, BIOS/UEFI setup, and OS provisioning • Supported Windows Server administration tasks: user account management, basic AD operations, file/print services • Monitored server health metrics (CPU, memory, disk, network) and escalated anomalies to senior engineers • Gained practical exposure to data center floor operations, structured cabling, and hardware troubleshooting under production conditions
