I help startups and small teams ship faster and sleep better — by building rock-solid AWS infrastructure and wiring AI into the ops work that used to eat entire days. A few results from my work as an SRE/DevOps engineer (6 years, AWS-primary): • Cut vulnerability analysis from 60 minutes to under 2 minutes with an AI-augmented workflow • Drove an 80% reduction in vulnerabilities through automated patching • Blocked 4 separate DDoS attacks with zero downtime • Cut manual intervention in CI/CD by 60% • Saved 25% on compute by moving from Cluster Autoscaler to Karpenter • Upgraded a production EKS cluster from v1.23 to v1.28 with zero downtime What I can do for you: • CI/CD pipelines that build, test, and deploy themselves (GitLab CI, Jenkins, GitHub Actions) • AWS architecture, EKS/GKE, Helm and ArgoCD — set up right, or rescued when it's broken • AWS cost optimization audits that find real, dollar-denominated savings • Terraform / Infrastructure-as-Code so your environment is reproducible and reviewable • Cloud security hardening — WAF, secrets management, VPC design, kernel patching • AI-augmented ops workflows that take repetitive SRE toil off your team's plate I work best with founders and small engineering teams in the US, UK, EU, and Australia who need senior infrastructure help without a full-time hire. I'm AWS Certified (Solutions Architect) and I deliver in clearly scoped milestones with async updates, so you always know the status without sitting in a meeting. Most of my engagements are fixed-price packages, so you know the cost up front. Tooling I use daily: AWS, Kubernetes (EKS/GKE), Terraform, Helm, ArgoCD, Karpenter, Docker, GitLab CI/CD, Jenkins, CloudFront, AWS WAF; Python, Go, and Bash; plus Claude and Codex for AI-augmented automation. You can see detailed case studies and my full project history at hemanthakumar.dev If you've got infrastructure that's slow, expensive, fragile, or on fire — send me a message with what's going on and I'll tell you honestly whether I can help and how I'd approach it.

10+ years building and operating production AWS infrastructure — from zero-downtime migrations to self-healing Kubernetes clusters that teams stop worrying about at 2 AM. I specialize in AWS DevOps and Site Reliability Engineering for companies that need their cloud infrastructure to be fast, cost-efficient, and genuinely reliable. Whether you need a Terraform-managed environment built from scratch, an on-prem workload migrated to AWS, or an SRE practice that actually reduces incidents — I've done all of it, across multiple industries. What I can deliver for you: ✦ Infrastructure as Code — Production-grade Terraform modules, reusable across environments (dev/staging/prod), with full state management, remote backends, and drift detection built in. ✦ Kubernetes & EKS — Cluster design, autoscaling, Helm chart management, GitOps with ArgoCD/Flux, and cost optimization. I set up clusters that developers love deploying to. ✦ CI/CD Pipelines — End-to-end automation using Jenkins, GitHub Actions, or AWS CodePipeline. Zero-downtime blue/green and canary releases. Pipelines that run in minutes, not hours. ✦ AWS Migration — Full lifecycle on-premise to AWS migrations: assessment, architecture, phased execution, and cutover with minimal downtime. Done this for monoliths and microservices alike. ✦ Monitoring & Observability — CloudWatch dashboards, Grafana/Prometheus stacks, Datadog APM, alerting that pages the right person at the right threshold — not noise. My approach on every engagement: I treat your infrastructure as if I'm on-call for it. That means documentation that your team can follow, runbooks for common failure scenarios, and no black-box setups that only I understand. When the contract ends, your team owns it. Open to: → Short-term projects (audits, migrations, pipeline builds) → Long-term retainers (ongoing SRE support, on-call backup, platform ownership) Tools & stack: AWS (EC2, EKS, ECS, RDS, S3, Lambda, CloudFront, VPC, IAM, Route53, CloudWatch) · Terraform · Kubernetes · Docker · Helm · ArgoCD · Jenkins · GitHub Actions · Prometheus · Grafana · Datadog · Ansible · Python · Bash · Linux If you're evaluating engineers for an AWS or DevOps role, let's talk.
