Your last DevOps person left and nobody knows how the infrastructure works. I've spent 8 years fixing exactly that for SaaS companies - Paramount+, LexisNexis, and three active clients right now. Top Rated Plus, 100% Job Success Score. ───── 🔧 I pick up where the last person left off. Your previous engineer quit, left half-finished Terraform and a pipeline migration that never got completed? I've walked into that exact situation at three companies this year. I absorb context fast, finish what they started, and hand your team a platform they can actually operate without me. If that sounds like your situation, send me a message with what's broken. I'll tell you what the fix looks like. 📋 Fixed scope. Clear outcome. 4-6 weeks. You know what you're getting and what it costs before we start. When I'm done, your infrastructure is codified in Terraform, your deployments are automated, and your team has operational documentation good enough that your junior engineers can run it. 30-day support window included after delivery. One client rebuilt their entire platform from zero in 79 minutes because of what I built. Another client raised my rate 40% on their own - I didn't ask. ☁️ AWS, GCP, Azure - whatever your stack needs. Kubernetes, ArgoCD, Linkerd, GitHub Actions, Azure DevOps. But you're not hiring me for tool names. You're hiring me so your infrastructure stops being the thing that keeps you up at night and starts being the reason you close enterprise deals. ───── ⭐ Government SaaS (Multi-Tenant Platform) -- Built the entire AKS platform from scratch. Linkerd service mesh enforcing mTLS tenant isolation. ArgoCD GitOps -- onboarding a new tenant is three config files. Full platform rebuild validated at 79 minutes. ⭐ Legal Tech SaaS -- Inherited half-finished Terraform fragments that didn't match what was running. Refactored into clean modules, built cross-cloud DR across GCP and AWS, automated deploys through GitHub Actions. Client raised my rate 40% unprompted. ⭐ Healthcare Finance SaaS -- Embedded after their DevOps engineer quit. 93+ PRs across 25+ repos in 5 months. JSON validation, pipeline migration, centralized templates, README enforcement org-wide. ───── If you've got infrastructure problems piling up and nobody to pick them up - send me a message and let's figure out the fix.

Free AWS audit upfront. Full refund on the first milestone if you're not satisfied. 100+ AWS migrations. Zero unplanned downtime. Cloud costs cut by up to 60%. SOC 2 passed after a 30-day security audit. I am Ibrahim, a senior AWS DevOps engineer with 9+ years building, securing, and scaling cloud infrastructure for SaaS platforms, fintech teams, and e-commerce companies. I specialize in AWS, Kubernetes (EKS), Terraform, Docker, CI/CD pipelines, and cloud security What I’ve already done in environments like yours: Migrated 100+ production environments from EC2 to EKS with zero unplanned downtime. Full Kubernetes orchestration with Docker containers, Helm charts, and Terraform-managed infrastructure as code across multi-region AWS architectures. Cut CI/CD deployment time from 4 hours to 12 minutes using GitHub Actions and GitLab CI/CD with blue-green deployment, automated rollback, and ArgoCD-driven GitOps workflows. Reduced AWS cloud costs by 30 to 60 percent through EC2 right-sizing, spot instance strategy, auto-scaling groups, Lambda serverless optimization, and ECS Fargate consolidation. Average client savings: $4,200 per month. Cleared 44 of 47 AWS security findings in 30 days for a fintech client. Passed SOC 2 Type I on the first attempt with full compliance controls across IAM, CloudTrail, GuardDuty, WAF, Security Hub, and AWS Config. Built HIPAA-compliant Kubernetes infrastructure on EKS with encrypted RDS databases, VPC isolation, private subnets, and continuous compliance monitoring via Prometheus, Grafana, and Datadog. Managed AWS EKS infrastructure for 30+ client environments with 99.9 percent uptime, zero major outages, and full observability with CloudWatch, ELK Stack, and Prometheus alerting. Designed multi-region AWS architectures handling 50,000+ concurrent users for e-commerce and fintech platforms using EKS, CloudFront, S3, RDS, ElastiCache, and Route 53. I'll work best with you if you are: A SaaS or fintech team whose AWS bill keeps growing. You need DevOps cost optimization, EC2 right-sizing, and cloud infrastructure cleanup. An engineering team that needs Kubernetes (EKS) built, secured, and maintained without a full-time DevOps hire. I handle Docker containerization, Helm charts, and container orchestration. A CTO scaling fast who needs AWS infrastructure that will not break under load. Auto-scaling, load balancing, multi-AZ failover, and high-availability architecture. A company preparing for SOC 2, HIPAA, or ISO 27001 compliance. I build cloud security controls, DevSecOps pipelines, and audit-ready AWS environments from scratch. A team migrating from legacy EC2, on-premise servers, or Elastic Beanstalk to Terraform-managed, containerized infrastructure on EKS or ECS with full CI/CD automation AWS DevOps & Cloud Security for Compliance-Ready Teams: I'll help you build AWS cloud infrastructure that is fast to ship, hard to break, and ready for serious security and compliance demands. My core strength is turning your aws environments into secure, compliant, production-ready platforms with strong AWS cloud security, DevSecOps, and clear controls for SOC 2, HIPAA, and ISO 27001. I work with your existing tech stack: AWS | Kubernetes / EKS / GKE | Terraform | Ansible | Docker | CI/CD | GitLab CI/CD | GitHub Actions | CodePipeline | Prometheus | Grafana | Datadog | Security Hub | GuardDuty | WAF | Shield | IAM | CloudTrail | ELK Stack | GCP How to Get Started: Send me a message with a quick overview of your AWS environment, your biggest infrastructure pain point, and where you want to be in 30 days. I will reply with a clear DevOps action plan. No pitch. Just what I would do differently with your Kubernetes clusters, your Terraform configs, your CI/CD pipeline, and your cloud security posture.
