Your AWS bill is growing faster than your revenue. Deployments take too long. Your infrastructure wasn't built to handle what you're throwing at it now. Sound familiar? I'm Nouman, a Certified AWS Cloud Architect with 7+ years of hands-on experience building production infrastructure that scales without breaking the bank. I've helped companies reduce their cloud spend by up to 40% while actually improving reliability and deployment speed. What I do best: → AWS Cost Optimization: I audit your infrastructure, kill waste, right-size resources, and implement Reserved Instance and Savings Plan strategies. Most clients see 30-40% savings within the first month. → Cloud Architecture & Migration: I design and build multi-cloud environments on AWS and Azure that are secure, scalable, and don't require a dedicated team to maintain. → Kubernetes & Containers: Private EKS and AKS clusters with GitOps workflows (ArgoCD, Karpenter, Terragrunt). Your team deploys with confidence, not anxiety. → CI/CD Pipelines: End-to-end automation with GitHub Actions, GitLab CI, and Azure DevOps. I've cut deployment cycles from hours to minutes for multiple clients. → Infrastructure as Code: Everything in Terraform and Terragrunt. Reproducible, version-controlled, and auditable. No more snowflake servers. Recent results: Optimized a multi-tenant AWS environment, cutting monthly spend by ~35% while improving uptime Built private Kubernetes clusters (EKS/AKS) serving production workloads with zero-downtime deployments Automated infrastructure provisioning that reduced environment setup from days to under an hour Implemented security and compliance frameworks (HashiCorp Vault, SonarQube, Trivy) for regulated industries How I work: I communicate clearly, respond fast, and treat every project like a partnership. I'll tell you what you need to hear, not just what you want to hear. That's how we get results. Ready to stop overpaying for AWS? Send me a message and let's talk about your infrastructure.

Your server is down. Your team is stuck. Your infrastructure is holding your business back. That's where I come in. I'm a Senior Systems Administrator with 10+ years of hands-on experience managing Linux and Windows server environments for enterprise-scale operations including 7 years at Nayatel, one of Pakistan's largest ISPs, where I owned infrastructure serving thousands of concurrent users. I've migrated complex on-premise systems to cloud environments with zero downtime, hardened servers against real threats, and built automation pipelines that eliminated hours of manual ops work every week. ━━━━━━━━━━━━━━━━━━━━━━━━ WHAT I HELP YOU WITH ━━━━━━━━━━━━━━━━━━━━━━━━ Server Setup & Administration Linux (Ubuntu, CentOS, RHEL) and Windows Server provisioning, configuration, patching, and troubleshooting. You get a stable, optimized server not just one that's running. Cloud Infrastructure (AWS & Azure) Deployments, migrations, cost optimization, and ongoing management. I hold AWS Solutions Architect and CloudOps certifications and have managed multi-cloud environments in production. Security & Hardening Firewall configuration, OS hardening, intrusion detection (Wazuh, ELK Stack), SSL/TLS, VPN setup, and penetration testing. I don't just set it up, I make sure it stays locked down. Automation & DevOps Support Terraform, Ansible, Docker, Kubernetes, CI/CD pipelines. Repetitive manual tasks get automated. Deployments become consistent and reliable. Database & Network Operations PostgreSQL, MySQL, MariaDB administration. DNS management, email servers (Zimbra, Axigen), routing, and VPN configuration. ━━━━━━━━━━━━━━━━━━━━━━━━ WHY CLIENTS WORK WITH ME AGAIN ━━━━━━━━━━━━━━━━━━━━━━━━ Most infrastructure freelancers disappear after delivery. I don't. I document everything, explain what I did and why, and stay available if something comes up after handoff. Two decades of enterprise ops work taught me that reliability is the job, not just technical skill. I keep communication clear and direct. No jargon dumps. No vague updates. You'll always know exactly where things stand. ━━━━━━━━━━━━━━━━━━━━━━━━ CERTIFICATIONS ━━━━━━━━━━━━━━━━━━━━━━━━ AWS Certified Solutions Architect – Associate AWS Certified CloudOps Engineer – Associate AWS Certified Cloud Practitioner Microsoft Certified: Azure Fundamentals Certified Kubernetes Administrator (CKA) ━━━━━━━━━━━━━━━━━━━━━━━━ LET'S TALK ━━━━━━━━━━━━━━━━━━━━━━━━ If your infrastructure needs to be more stable, more secure, or better managed, send me a message.

If your engineering team is shipping slower than six months ago and your AWS bill is growing faster than your revenue the problem is almost never the engineers. It's the infrastructure they're working around. I fix that at the architecture level, not the band-aid level. I'm a Top Rated DevOps and Cloud Security Engineer (100% JSS) who has worked with Series A–C SaaS companies, high-volume e-commerce platforms, and regulated fintech environments across AWS, Oracle, and Azure. Recent engagements: ✔ Reduced deployment time from 4 hours to 85 minutes (65% faster) for a SaaS platform at 500k MAU ✔ Cut AWS spend by 40% ($18k/month saved) for a $30M ARR e-commerce company through E KS right-sizing, spot instance migration, and auto-scaling architecture. ✔ Maintained 99.98% uptime for a Series B fintech platform processing $2M+/day — through Prometheus + Grafana alerting, SLO definition, and proactive SRE incident runbooks. Here's the infrastructure automation and cloud engineering work I do best: ✔ CI/CD & Automation : Jenkins, GitHub Actions, GitLab CI. From commit to production in minutes, not hours. ✔ Kubernetes & Container Orchestration : Docker, K8s cluster setup, scaling, and hardening on AWS EKS, GKE, and AKS. ✔ Infrastructure as Code : Terraform and Ansible. Reproducible, version-controlled infra from day one. ✔ Cloud Security & DevSecOps : Threat modelling, IAM hardening, EBS encryption, VPN, and SSL/TLS across AWS, GCP, and Azure. ✔ Observability : Prometheus, Grafana, ELK Stack. You see problems before your users do. I don't just implement what's asked. I assess whether what's asked is the right solution. When Terraform is overkill, I'll say so. When Kubernetes is being used where Docker Swarm would serve better, I'll tell you before you spend three months over-engineering it. My value is in the decisions that don't make it into the ticket not just the ones that do. I take on 2–3 engagements at a time and I'm selective about fit. If you're dealing with infrastructure that's becoming a ceiling on your growth share your architecture overview or describe the problem. I'll come back with a direct technical perspective within one business day. If it's not something I can solve well, I'll tell you that too. 💬 Send me a message with your stack AWS, GCP, Azure, Kubernetes, or Linux and your biggest DevOps or cloud security challenge. I'll respond within 2 hours with a direct technical assessment. No sales pitch, no discovery call needed.
