Live deployment

A portfolio that proves the deployment habit.

Every update starts with Git and ends behind CloudFront. The flow is intentionally simple, but it shows the same operating pattern hiring teams want: versioned changes, repeatable releases, private origin storage, HTTPS at the edge, and cache invalidation after deployment.

Release path

push to main
  1. 01 GitHub Private repo receives a commit on main.
  2. 02 Actions Workflow validates secrets and assumes the AWS role.
  3. 03 S3 Static files sync to the private site bucket.
  4. 04 CloudFront The edge cache is invalidated for fresh content.
  5. 05 Route 53 DNS routes visitors to the distribution.

Workflow core

fast run 
aws-actions/configure-aws-credentials@v6
role-skip-session-tagging: true

aws s3 sync . s3://nettechshifat.cloud --delete

aws cloudfront create-invalidation \
  --distribution-id E3FHE2OLFKHR7N \
  --paths "/*"
Source Private GitHub repo

Content changes are versioned, reviewed, and deployed from Git.

Origin Private S3 bucket

The bucket stays behind CloudFront instead of public website hosting.

Edge CloudFront HTTPS

Requests terminate at the CDN with cache invalidation after release.

Domain nettechshifat.cloud

Route 53 and CloudFront serve the personal DevOps site.

About

Practical DevOps support for teams that need reliable delivery.

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, ELK Stack, and Zabbix to improve alerting, diagnostics, log analysis, and platform insight.

High-availability platform support

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

Skills

Skills organized around real infrastructure work.

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, ELK Stack, and Zabbix for monitoring, alerting, log analysis, 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

Featured security IaC project

Wazuh on AWS with repeatable rollout and safer recovery.

A production-style Wazuh deployment built with Terraform, Packer, GitHub Actions, Docker, EBS, internal DNS, and snapshot-based recovery workflows.

Terraform / Packer / GitHub Actions / AWS

Built an IaC-driven Wazuh platform with persistent data outside the Auto Scaling lifecycle.

The stack separates Wazuh indexer, manager, and dashboard into their own Auto Scaling Groups while keeping each role's data on standalone EBS volumes. Instances can be refreshed or replaced from a new AMI without throwing away security monitoring data.

  • Terraform modules
  • Packer AMI builds
  • Docker Compose runtime
  • Internal NLB
  • Route 53 private DNS
  • MFA-based GitHub Actions
  • Snapshot restore
Roles Indexer, manager, dashboard
Recovery Snapshot set restore flow
Safety EBS prevent-destroy guardrails
  • Created a shared Debian 12 Wazuh AMI with Docker Engine, Compose, baked runtime files, certificates, and version metadata.
  • Automated plan, apply, rollout-only, destroy, and restore-from-snapshot workflows through GitHub Actions.
  • Preserved role data volumes during instance refreshes and destructive workflows to reduce accidental data loss risk.

Projects

Project evidence for hiring conversations.

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

Git-based delivery

Personal site deployment on S3 and CloudFront

GitHub Actions / AWS

Built a private-repo deployment path for this site where every push to main syncs static assets to S3 and invalidates the CloudFront distribution serving nettechshifat.cloud.

  • Configured GitHub Actions with AWS credentials and role assumption
  • Synced repository files to S3 with deletion of removed assets
  • Invalidated CloudFront automatically after each successful deploy
Outcome Manual uploads were replaced with a repeatable Git-based deployment workflow.

Security monitoring

Wazuh IaC on AWS with Terraform and Packer

Terraform / Packer / Wazuh

Built a repeatable Wazuh security monitoring platform on AWS with role-based Auto Scaling Groups, persistent EBS data volumes, AMI automation, private DNS, and GitHub Actions deployment workflows.

  • Separated indexer, manager, and dashboard roles across dedicated ASGs and internal endpoints
  • Used Packer to build a shared Debian 12 AMI with Docker, Wazuh runtime files, and generated certificates
  • Added snapshot, rollout-only, destroy-with-preserved-data, and restore-from-snapshot operations
Outcome Wazuh became easier to upgrade, recover, and operate without rebuilding monitoring data by hand.

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
Outcome Application hosting had clearer routing, safer access rules, and better operational 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
Outcome Build and deployment work moved from manual steps toward predictable pipeline execution.

  • Implemented Nagios, Grafana, ELK Stack, and Zabbix-based health visibility
  • Maintained HAProxy and database components for high availability
  • Contributed to DR drills and ISO27001 and ISO22301 support work
Outcome Teams had stronger signals for incidents, availability, and recovery readiness.
