Project 1: Solution Support-L2 Operations (Client-Facing) | 01/2018 – 04/2021

• Installed, updated, and configured software packages and OS patches on on-prem Linux and Windows servers to maintain system stability.
• Executed Ansible ad-hoc commands (e.g., ansible -m ping, package installs, service restarts) and authored reusable YAML playbooks for OS hardening, package updates, and service deployments.
• Performed daily Linux administration tasks such as file management, log analysis (grep, tail, cat), and SSH-based remediation.
• Managed LVM storage by provisioning and resizing volumes using tools like fdisk, lsblk, pvcreate, vgcreate, lvcreate, and mkfs.
• Developed Bash scripts for health checks, log rotation, and disk cleanup, reducing manual effort by approximately 25%.
• Monitored server health using Zabbix, tuning alerts for CPU, memory, and disk usage; resolved incidents within an average of 60 minutes.
• Supported Windows environments by managing services via Command Prompt and Event Viewer, handling network-share permissions, and applying OS and security updates.
• Provisioned and configured AWS EC2 instances within VPCs, set security group rules, and managed IAM roles and policies for support personnel.
• Configured and troubleshot Linux network interfaces, assigned IPv4 addresses, DNS settings, and routes using nmcli, resolving connectivity issues.

Project 2: DevOps & Cloud Support– E-commerce Platform for Biometric Products | Apr 2021 – Jun 2024

• Provided Level 2 support for AWS services (EC2, S3, RDS, IAM, VPC) across a 50+ node environment.
• Managed incident tickets using Jira and ServiceNow, handled escalations from Level 1 support, defined workflows, tracked SLAs, and generated stakeholder reports.
• Developed Bash scripts and assisted in developing Python scripts for automating Linux operational tasks such as node health checks, log rotations, and service monitoring, reducing manual intervention
• Assisted in provisioning and scaling AWS resources using Terraform, creating reusable modules and applying environment-specific configurations.
• Extended and maintained Ansible playbooks to automate cloud server configuration, patching, and deployments across development, staging, and production environments.
• Supported and maintained Jenkins CI/CD pipelines by reviewing build logs, troubleshooting issues, integrating automation scripts for rollback and notifications, and merging pull requests.
• Supported containerized application deployments using Docker and AWS ECS, improving deployment consistency and reducing resource costs by around 5%.
• Monitored cloud resources using AWS CloudWatch ; helped automate alert-based ticket creation in Jira.
• I participate in Scrum meetings to provide updates and coordinate issue resolutions with developers and DevOps teams. I also manage on-call issues that are notified to me via Slack alerts from monitoring systems

• Deploy and maintain Linux servers (RHEL, CentOS, Ubuntu): disk partitioning, LVM and filesystem creation (ext4), and networking configuration (nmcli, static IPs, routing, DNS)
• Automate system tasks with Bash scripts and manage configuration with Ansible playbooks and ad-hoc commands, scheduled via crontab
• Perform and automate backups using rsync and tar, scheduled via crontab
• Administer user accounts, groups, permissions, and secure file transfers (useradd/usermod/groupadd, chmod/chown, SCP/SFTP)
• Provision and manage AWS infrastructure (EC2 instances, IAM users and policies, Security Groups, S3 buckets)
• Install, update, and remove software packages using YUM and APT
• Monitor service status and analyze logs—real time with tail -f /path/to/logfile and periodic review of system logs (e.g. /var/log/syslog or /var/log/messages) for production support and troubleshooting

• Managed Active Directory user accounts and domain-joined Linux/Windows workstations; deployed standardized system images using Clonezilla.
• Installed and configured Oracle SQL clients; performed CRUD operations using SQL Developer (SELECT, INSERT, UPDATE, DELETE).
• Applied Linux updates, provisioned packages, managed services, and performed system hardening; analyzed system logs and processes.
• Administered Linux servers remotely over SSH; handled secure file transfers using scp.
• Set up and maintained Apache web server, including configuration, deployment, and troubleshooting.
• Monitored system performance and availability using Zabbix across Production, Staging, and Development environments.
• Oversaw disk usage and database size in on-premise environments; ensured storage optimization and uptime.
• Supported Windows OS by installing updates and managing services on standalone and clustered servers (as part of mixed-environment support).
• Provided 24/7 monitoring and incident response for Linux and Windows servers in rotational shifts.
• Experienced in installation, configuration, administration, troubleshooting, performance tuning, patching, backup/recovery, and upgrade of Linux servers in medium-scale production environments.
