Work Experience

May 2025 – Aug 2026

Cloud & Infrastructure Support Engineer

LTM Limited — Hyderabad

Owned day-to-day cloud and infrastructure support across AWS and Azure in a 24x7, SLA-driven environment — keeping servers, networks and services healthy, resolving incidents end to end, and running the patching, backup and access operations that kept the estate stable. Here is how that work broke down:

☁️ Cloud Platform Operations — AWS & Azure AWS · Azure

Supported day-to-day operations of AWS EC2 instances — handling start/stop/reboot requests, resizing and status-check failures, troubleshooting instances that became unreachable, and validating recovery after host-level issues.
Worked on AWS S3 for bucket and object-level tasks including storage access issues, permission and policy troubleshooting, and lifecycle-related queries raised by application teams.
Administered Azure Virtual Machines end to end — provisioning from approved templates, resizing, managing disks, troubleshooting boot and agent failures, and using serial console and boot diagnostics when VMs failed to come online.
Handled Azure Storage operations covering storage accounts, blob containers, file shares, access keys and SAS tokens, along with capacity and access-related troubleshooting.
Applied AZ-104 knowledge in live environments across subscriptions, resource groups, tagging standards and resource lifecycle management, keeping resources aligned to naming and governance conventions.

🖥️ Server & Operating System Administration Linux · Windows

Administered Linux servers — user and group management, file and directory permissions and ownership, service management via systemd, log review under /var/log, and mount point and partition checks.
Managed Windows Servers including services, roles and features, Event Viewer analysis, Task Scheduler jobs and remote administration over RDP.
Performed scheduled system health checks across CPU, memory, disk utilisation, running services and uptime, flagging deviations before they turned into outages.
Troubleshot disk and capacity issues — identifying filesystems approaching thresholds, locating oversized and stale files, clearing archived logs, and raising disk-extension requests with storage teams.
Investigated performance degradation using tools such as top, df, du, free and Windows Performance Monitor to isolate whether the bottleneck sat in CPU, memory, disk I/O or a runaway process.

🛠️ Patch Management & Scheduled Maintenance Patching

Executed OS patching cycles for Linux and Windows servers during approved maintenance windows, working to agreed change schedules.
Ran pre-patch checks — confirming backup completion, capturing baseline service and application states, verifying free disk space, and validating server accessibility before the window opened.
Performed post-patch validation after reboots: confirming servers returned online, services and scheduled tasks restarted cleanly, monitoring agents reported healthy, and applications were reachable.
Coordinated reboot sequencing with application and database teams so dependent systems restarted in the correct order and downtime stayed inside the approved window.
Tracked patch compliance and followed up on servers that failed or missed their patch cycle, re-scheduling them and documenting the reason for the miss.
Supported vulnerability remediation by applying security patches flagged in scan reports and confirming closure back to the security team.

💾 Backup, Restore & Recovery Operations Backups

Monitored scheduled backup jobs daily, reviewing job dashboards and reports to confirm successful completion across servers and VMs.
Investigated failed and partially completed backup jobs — checking agent status and connectivity, media and target availability, credential expiry and storage capacity — then re-triggered jobs after fixing the cause.
Supported restore requests for files, folders and volumes, validating restored data with the requesting team and confirming integrity before closing the ticket.
Managed VM snapshots before risky changes such as patching or configuration updates, and cleaned up stale snapshots to reclaim storage.
Participated in backup and recovery validation activities, performing test restores to confirm recovery procedures worked as documented for business continuity readiness.

🌐 Network & Connectivity Troubleshooting Networking

Diagnosed connectivity issues using ping, traceroute, telnet, nslookup, netstat and Test-NetConnection to determine whether a failure sat at the network, host, port or application layer.
Resolved DNS-related problems including name-resolution failures, stale records and incorrect resolver configuration, coordinating record updates with the network team where required.
Worked on TCP/IP fundamentals in practice — IP addressing, subnetting, gateways, routing behaviour and port-level reachability checks.
Supported Azure VNet and AWS VPC configurations covering subnets, route tables, NSGs and security groups, troubleshooting cases where traffic was blocked by misconfigured rules.
Handled firewall and VPN escalations by gathering source/destination/port evidence and raising well-documented requests to the network security team for rule changes.

🔐 Identity & Access Management AD · Entra ID

Processed user access requests covering account creation, modification, disabling and deletion in line with approval workflows.
Administered Active Directory objects — users, groups, organisational units and group memberships — and resolved account lockouts, password resets and stale-account cleanups.
Managed identities in Microsoft Entra ID, including user and group management, licence assignment, sign-in log review and troubleshooting authentication failures.
Implemented RBAC assignments in Azure at subscription and resource-group scope, applying least-privilege principles so users received only the access their role required.
Assisted with MFA support — registration, device re-enrolment and resolving sign-in failures — and supported periodic access reviews to remove entitlements no longer needed.

📊 Monitoring, Alerting & Observability Azure Monitor · Dynatrace

Monitored infrastructure health continuously through Azure Monitor and Dynatrace, working from live dashboards across a shift-based support model.
Handled alert triage — acknowledging incoming alerts, assessing severity and business impact, actioning known alerts against runbooks, and escalating genuine issues quickly.
Responded to threshold breaches for CPU, memory, disk and service availability, investigating the underlying cause instead of simply clearing the alert.
Performed log analysis across system, application and platform logs to correlate alerts with real events and establish an accurate timeline during incidents.
Reduced alert noise by identifying repeat and false-positive alerts and recommending threshold or configuration adjustments to the monitoring team.
Carried out proactive health checks at shift start and handover, catching developing issues before users reported them.

🎫 Incident, Request & Change Management ServiceNow · ITIL

Managed incidents in ServiceNow across the full lifecycle — logging, categorising, prioritising by impact and urgency, investigating, resolving and closing with accurate resolution notes.
Fulfilled service requests such as access provisioning, resource creation, configuration changes and reporting, working strictly within defined approval paths.
Worked to SLA targets, tracking response and resolution clocks, prioritising queues by breach risk, and escalating early when a ticket trended toward breach.
Followed structured escalation procedures, handing over to L2/L3 and specialist teams with complete context — symptoms, steps already taken, findings and business impact — so no time was lost repeating work.
Supported change management by raising and documenting change records, attaching implementation and rollback plans, and executing approved changes inside maintenance windows.
Contributed to problem management by identifying recurring incident patterns and flagging them for permanent fixes rather than repeated workarounds.
Applied ITIL processes consistently across incident, request, change and problem workflows in a structured enterprise support environment.

⚙️ Automation, Scripting & Tooling PowerShell · Azure CLI

Used PowerShell for routine administrative tasks — querying service and process states, checking disk space across servers, pulling AD user details and automating repetitive checks.
Worked with Azure CLI to query and manage Azure resources, validate configurations and retrieve resource details faster than through the portal.
Applied basic Bash scripting on Linux for log parsing, scheduled housekeeping and repeated health-check commands.
Automated recurring manual checks to cut repetitive effort during shifts and reduce the chance of human error in routine validation.
Administered systems remotely over RDP and SSH, including key-based authentication and jump-host access to restricted environments.

📘 Documentation, SOPs & Team Collaboration SOP · Runbooks

Executed approved SOPs and runbooks for infrastructure checks, troubleshooting and incident resolution, ensuring consistent and auditable outcomes across the team.
Authored and updated technical documentation — troubleshooting steps, known-error entries and resolution guides — so recurring issues could be solved faster by anyone on shift.
Delivered structured shift handovers, passing on open incidents, ongoing activities and pending follow-ups so nothing was dropped between shifts.
Collaborated with application, network, database, security and cloud teams during major incidents, contributing infrastructure-side findings to reach resolution quickly.
Communicated clearly with end users and stakeholders, providing status updates during outages and translating technical detail into plain language.
Worked effectively under pressure in a 24x7 shift-based environment, staying methodical during high-severity incidents and outage situations.
