About Me & Philosophy

Bridging the gap between software development and rock-solid cloud infrastructure.

DevOps Mindset & Foundation

I am Saad Hassan Qureshi, a passionate DevOps and Cloud Infrastructure Specialist currently pursuing my Bachelor of Science in Computer Science (2024 – 2028). I unite deep computer science and networking fundamentals with modern automated cloud practices.

With practical industry experience as a Junior DevOps Specialist Intern at Burjsoft (May 2026 – August 2026) and formal certification under the Honhaar Jawan Program (Government of Pakistan), I engineer systems designed for high availability, automated security (DevSecOps), zero downtime, and fast rollbacks.

Featured DevOps Projects

Real-world infrastructure code, Kubernetes setups, and zero-downtime automation.

01 / AWS & IaC Production Ready

Multi-Tier AWS Web Infrastructure with Terraform & EKS

Designed and provisioned a multi-AZ AWS architecture utilizing Terraform. Includes public/private subnets, NAT Gateways, an Amazon EKS managed Kubernetes cluster, and RDS PostgreSQL with automated snapshots.

✔ 100% Declarative Infrastructure as Code (Terraform)
✔ Secure private subnets with IAM Least-Privilege roles
AWS EKSTerraformVPCRDSIAMNAT Gateway
02 / CI/CD & GitOps Automated

End-to-End Automated GitOps Pipeline (Actions + ArgoCD)

Created a declarative CI/CD pipeline where code commits trigger automated testing, multi-stage Docker image builds with Trivy security scans, and ArgoCD synchronization for zero-downtime Kubernetes deployments.

✔ Fully automated Git-to-production deployment cycle
✔ Security vulnerability scanning integrated into CI
GitHub ActionsArgoCDDockerKubernetesTrivy
03 / Kubernetes High Availability

Production Kubernetes Cluster with Ingress & Cert-Manager

Configured a highly scalable microservices cluster with NGINX Ingress Controller, automatic SSL/TLS certificate generation via Let's Encrypt / Cert-Manager, and Horizontal Pod Autoscaling (HPA) based on CPU/memory load.

✔ Automated SSL renewal with Cert-Manager
✔ Dynamic traffic distribution and Horizontal Pod Autoscaling
KubernetesHelmNGINX IngressCert-ManagerHPA
04 / Linux Security Hardened

Enterprise Linux Server Hardening & Security Automation

Developed automated Bash automation suites to enforce CIS security benchmarks across Ubuntu and RHEL servers: custom IPTables/UFW rules, SSH key-only access, Fail2ban intrusion prevention, and automated system patching.

✔ 90% reduction in brute-force attack vectors via Fail2ban
✔ Automated compliance auditing and root login prohibition
Linux (Ubuntu/RHEL)Bash ScriptingIPTablesFail2banSSH
05 / Observability Monitoring

Full Observability Stack with Prometheus, Grafana & Loki

Deployed a centralized monitoring and log aggregation stack across Linux servers and Kubernetes workloads. Built custom Grafana dashboards for CPU, memory, network I/O, and integrated Alertmanager for incident notifications.
