Adnan Saif Ansari

Provisioned and managed
multi-cloud infrastructure
(AWS EC2, S3, VPC, RDS; Azure VMs, NSGs) using Terraform andCloudFormation across 3+ client environments, ensuring environment consistency and zero-drift deployments.
Designed and maintained
CI/CD pipelines
using GitHub Actions and AWS CodeBuild, cutting deployment time by
35%
andreducing failed releases through automated testing gates.
Deployed and operated
containerized microservices on AWS EKS
using Docker, Kubernetes, and Helm charts, supporting high-availability production workloads for enterprise clients.
Built and configured
OpenShift clusters from scratch
on bare metal and Azure (ARO), including node provisioning, networkingsetup (ingress controllers, routes, SDN), and cluster hardening — delivering a production-ready environment for a client from day zero.
Managed
OpenShift service accounts, RBAC policies, secrets, and tokens
to enforce least-privilege access and secure application-to-cluster communication across multi-tenant workloads.
Deployed and managed client microservices on
OpenShift
using Helm charts and YAML manifests via
oc CLI
; troubleshot node andpod-level failures, maintaining cluster uptime and minimizing service disruption.
Integrated
OpenShift pipelines with CI/CD workflows
and configured monitoring and alerting for cluster health, achievingconsistent production reliability for the client environment.
Embedded
SonarQube and Checkmarx
into CI/CD pipelines for automated code quality and security scanning, improvingdeployment success rate by
30%
and ensuring compliance with client security standards.
Automated infrastructure workflows using
Bash and Python
scripts and configured end-to-end observability with Prometheus, Grafana, and CloudWatch — reducing manual operational effort by
40%
.
Performed
daily system health checks
across Linux servers monitoring CPU, memory, and file system utilization; troubleshot andresolved utilization breaches to maintain production stability for multiple clients.
Implemented
Ansible-based automated patching
across server fleets, ensuring consistent compliance, reduced patch windows, andminimal service disruption.
Administered
Azure VM operations
including VM resizing, snapshot creation and deletion, and Privileged Identity Management(PIM) access; used Azure Serial Console for VM recovery and access troubleshooting.
Managed
SolarWinds maintenance mode scheduling
for planned activities and upgraded Syslog NG Storage Box to enhancecentralized logging and monitoring capabilities across client environments.
Led
on-premises to Azure cloud migration
activities for a logistics client, coordinating infrastructure cutover with near-zerounplanned downtime using blue-green deployment strategies.
Worked on
VMware tools
for virtual machine optimization, troubleshooting, and performance tuning across multi-client virtualizedenvironments.
Implemented
AWS tagging strategies and rightsizing recommendations
, achieving measurable cost optimization across client cloudaccounts.
Collaborated directly with client infrastructure and security

Administered and provisioned a fleet of
100+ Linux servers
(RHEL and Ubuntu) across hybrid on-premises and Azure environments, managing user accounts, permissions, and security policies end-to-end.
Executed
security hardening and automated patching cycles
across the server fleet using Bash scripting and Ansible playbooks, reducing patch window duration and maintaining zero data loss during patch failures via rollback strategies.
Implemented
disaster recovery protocols and server restoration procedures
, including snapshot-based recovery on Azure VMs andbare-metal restoration for on-premises systems, ensuring business continuity during critical incidents.
Engineered
24/7 system health monitoring
using Prometheus and Grafana for Linux infrastructure — tracking CPU, memory, disk, and network metrics — enabling rapid detection and resolution of high-priority infrastructure issues.
Collaborated with
cross-functional DevOps teams
to containerize applications using Docker and provision servers from scratch, streamlining deployment pipelines for modern cloud-native workloads.
Managed
LVM storage, file system operations, firewall rules, DNS, and DHCP
across hybrid infrastructure; performed kernelupgrades via RPM/YUM and ensured seamless connectivity between on-premises and Azure environments.
