Asif Khan | DevOps Engineer, Cloud Architect and Linux Systems Administrator

I build and run Linux and cloud infrastructure that stays up, ships often and doesn't quietly double the bill. Kubernetes, Terraform, CI/CD, AWS, Google Cloud and Azure, plus a lot of plain old Linux underneath all of it.

About me

I've spent 14 years on Linux systems, DevOps and cloud infrastructure.

It started with open source. You could open something up, see how it worked and fix it yourself, and I never really got over that. The curiosity became a career, and the career took me through a handful of industries. Building Linux environments. Running them in production. Nudging teams toward DevOps before most of them were convinced it was worth the trouble.

The work I like best is the unglamorous kind:

  • Systems that stay up at 3am without anyone watching them
  • Deployments that don't need a maintenance window
  • Infrastructure the next engineer can understand six months later without calling me

I also write about all of this at Linux Pathfinder, where I've published 82 hands-on guides on Linux administration, Kubernetes, Docker, Terraform and cloud. Most of them started as a problem I hit at work. So they include the parts that broke, not just the tidy version.


What I do

Cloud and system architecture. Highly available, scalable systems built for real traffic, on AWS, Google Cloud, Azure and smaller providers like DigitalOcean and Linode. Designed around the failure modes, because availability is the easy word and the outage is the real test.

Kubernetes and containers. Clusters built with kubeadm, Minikube and managed services (EKS, GKE). Ingress, ConfigMaps, Secrets, persistent storage and stateful workloads. Helm for repeatable releases.

Infrastructure as Code. Terraform first, with CloudFormation and Azure ARM when the platform calls for it. Versioned providers, locked dependencies and changes that go through review like any other code.

CI/CD and automation. Pipelines in Jenkins, GitHub Actions, GitLab CI/CD, Bitbucket Pipelines and AWS CodePipeline. Multi-stage builds, environment-driven config and zero-downtime releases. If a task happens twice, it gets scripted.

Security and reliability. Server hardening, IAM and least-privilege access, TLS done properly, and security checks inside the pipeline rather than bolted on at the end. Monitoring and alerting that tell you something useful.


Technical skills

Linux administration

Ubuntu, Debian, CentOS, Red Hat (RHEL), Fedora and Oracle Linux.

Day to day that means systemd services, LVM and disk management, file permissions and attributes, performance tuning, memory and cache troubleshooting, root password recovery, cron scheduling, and Bash scripting for whatever needs automating.

Cloud platforms

AWS, Google Cloud, Azure, DigitalOcean, Linode, Vultr and IONOS.

On AWS: EC2, RDS, ECS, EKS, Fargate, CloudWatch, CodePipeline, Application Load Balancer, IAM and Security Groups. On Google Cloud: GKE and the Cloud SDK.

Infrastructure as Code

Terraform, AWS CloudFormation and Azure ARM templates.

VPC networking, cluster provisioning, ingress controllers, Helm deployments and RBAC, all as code with pinned provider versions.

Containers and orchestration

Docker, Docker Swarm, Kubernetes and KVM.

Image and container lifecycle, cluster setup with kubeadm and Minikube, managed clusters on EKS and GKE, Helm charts, ingress, ConfigMaps, Secrets, persistent volumes and stateful apps.

CI/CD

Jenkins, GitHub Actions, GitLab CI/CD, Bitbucket Pipelines and AWS CodePipeline.

Jenkinsfile and .gitlab-ci.yml pipeline design, multi-stage build and deploy, Docker Compose for local and production parity, variable-driven environments, self-hosted runners and zero-downtime deployment strategies.

Configuration management

Ansible, Chef and SaltStack.

Databases

MySQL, MariaDB, PostgreSQL, MongoDB, Redis and AWS RDS.

Performance tuning, replication setup and repair, and migrations. Including the ones nobody wants to run on a Friday.

Web servers and application stack

Nginx, Apache, Apache Tomcat, HAProxy and PHP-FPM.

Node.js, Next.js, Java, PHP, Elasticsearch, PM2, Laravel, and WordPress at scale with custom themes, plugins and multisite.

Monitoring and observability

Prometheus, Grafana, ELK Stack, Nagios, Zabbix, AWS CloudWatch, New Relic, PRTG, Monit, Cacti, Munin and Cockpit.

Metrics, logs and alerting, plus the ongoing argument about what actually deserves to wake someone up.

Networking and security

BIND DNS, SSH key-based authentication, nmap, ss and netstat, IP addressing and subnetting, rsync and scp.

SSL/TLS with Let's Encrypt automation and CSR generation, Linux server hardening, firewalls, and DevSecOps practices built into CI/CD.

Mail servers

Postfix, Dovecot, SMTP, and DKIM, SPF and DMARC so the mail actually lands in the inbox.

Beyond the tooling

Project management and process improvement. Technical documentation and training that people actually use. IT operations and service management. Capacity planning and cloud cost control. And talking to stakeholders in plain language, without vanishing into jargon.
