Cloud and DevOps Engineer | AWS | Linux | Terraform | Docker

Building reliable cloud platforms and practical DevOps systems for production teams.

I am Md Shihab Hossain Shifat, a Dhaka-based Cloud and DevOps Engineer with hands-on experience across AWS infrastructure, Linux administration, CI/CD pipelines, Docker deployments, HAProxy, PostgreSQL, Wazuh, and monitoring stacks. I currently support production workloads at Metafour Ltd while continuing to deepen my Terraform and infrastructure-as-code practice.

About

Cloud, platform, and operations work grounded in real production support.

My experience spans AWS environments, Linux administration, multi-tenant production support, Java and PHP application deployment, Docker-based delivery, load balancing, database operations, backup and disaster recovery planning, and monitoring. I focus on making infrastructure easier to operate, more repeatable, and more dependable for the teams using it every day.

AWS infrastructure operations

Provision and support EC2, VPC, IAM, Auto Scaling, EBS, S3, Route 53, and load-balanced application environments.

CI/CD and release automation

Build and maintain GitHub Actions, GitLab CI/CD, Jenkins, and Bash-driven automation for more stable releases.

Monitoring and security visibility

Implement and troubleshoot Wazuh, Nagios, Grafana, and Zabbix to improve alerting, diagnostics, and platform insight.

High-availability platform support

Work with HAProxy, PostgreSQL clusters, Linux services, and operational runbooks to keep services available and recoverable.

Skills

Technical skills grouped by how I actually use them.

Instead of a flat keyword list, these are the tools and platforms I work with across cloud infrastructure, operations, automation, networking, and observability.

Cloud and infrastructure

  • AWS EC2, Lightsail, VPC, IAM, Auto Scaling, Route 53, S3, load balancers, and EBS
  • Infrastructure design for web applications, security groups, DNS, and production hosting

IaC and automation

  • Terraform for repeatable provisioning and security monitoring deployments
  • Bash scripting for operational automation and database backup workflows
  • Ansible at a foundational level

CI/CD and delivery

  • GitHub Actions, GitLab CI/CD, and Jenkins pipeline setup and maintenance
  • Docker-based application deployment and release process support

Linux and platforms

  • Red Hat, CentOS, SUSE, Oracle Linux, and Windows Server administration
  • Apache, Nginx, HAProxy, VMware ESXi, Hyper-V, and Oracle VirtualBox

Monitoring and security

  • Wazuh, Nagios, Grafana, and Zabbix for monitoring, alerting, and security visibility
  • Operational troubleshooting, service checks, log review, and incident support

Databases and networking

  • PostgreSQL 14, MySQL, Microsoft SQL Server, Oracle 19c, and Microsoft Access
  • TCP/IP, DNS, static IP configuration, MikroTik, Cisco switching, and CCNA fundamentals

Projects

Selected work from AWS deployments, monitoring stacks, and delivery pipelines.

These examples come directly from the kinds of systems I have deployed, maintained, or improved in production-style environments.

Security monitoring

Wazuh on AWS with Terraform

Terraform / Wazuh

Implemented infrastructure-as-code patterns for Wazuh security monitoring on AWS and supported the manager, indexer, dashboard, certificates, and service troubleshooting needed to keep the stack operational.

  • Worked with multi-node deployment and containerized Wazuh components
  • Handled connectivity issues, debugging, and practical rollout problems
  • Focused on secure deployment and repeatability instead of one-off setup

AWS application hosting

Production platforms for eboighar.com and a1queue.com

AWS / HAProxy

Managed AWS-based production infrastructure for live application environments, including compute, networking, DNS, SSL, load balancing, and database support.

  • Deployed e-commerce and queueing platforms on AWS infrastructure
  • Configured security groups, VPC connectivity, SSL, and Nginx or HAProxy routing
  • Supported environment consistency with Docker and operational runbooks

Release automation

GitLab and Jenkins CI/CD pipelines

CI/CD

Installed and configured local CI/CD platforms and built pipelines for PHP and container-based applications to reduce manual deployment work and improve delivery consistency.

  • Created reusable build and deployment flows for web applications
  • Supported GitHub Actions alongside Jenkins and GitLab CI/CD workflows
  • Automated operational tasks with Bash to support safer deployment cycles

Observability and resilience

Monitoring, HAProxy, PostgreSQL, and DR support

Monitoring

Supported platform reliability with monitoring dashboards, service checks, HAProxy load balancing, PostgreSQL cluster operations, backup workflows, and disaster recovery exercises.

  • Implemented Nagios, Grafana, and Zabbix-based health visibility
  • Maintained HAProxy and database components for high availability
  • Contributed to DR drills and ISO27001 and ISO22301 support work
