Hire the Best Kubernetes Developers

I've cut AWS bills by 60%, maintained 99.9% uptime across 50-node EKS clusters, and shipped SOC2-compliant infrastructure for FinTech and SaaS companies - across 6+ years of hands-on cloud engineering. Whether you're a startup drowning in cloud costs, a SaaS company outgrowing your Kubernetes setup, or an enterprise navigating a SOC2 or GDPR audit - I've solved that exact problem, with numbers to back it. ▸ Kubernetes & EKS Architecture I design production-grade EKS clusters built to scale multi-AZ, auto-scaling with Karpenter, Spot Instance optimized, and GitOps-driven deployment pipelines. I've supported engineering teams of 10–50 engineers with infrastructure that doesn't create 2am incidents. ▸ FinOps & Cloud Cost Engineering I don't just trim costs I restructure how cloud spend works. Slashed cluster compute costs 60% via Karpenter + EC2 Spot strategy. Reduced CI/CD infrastructure costs 35% by migrating Jenkins pipelines to GitHub Actions. ▸ DevSecOps & Compliance Built GDPR and SOC2 Type II compliant infrastructure from scratch Zero-Trust IAM, AWS WAF, automated secrets rotation, CloudTrail audit logging, and compliance documentation. Experienced with HIPAA and PCI-DSS-ready architectures for FinTech clients. ▸ Observability & Reliability Full monitoring stacks with Prometheus, Thanos, Loki, and Grafana SLO dashboards, alerting runbooks, and incident response playbooks. I build for 99.9%+ uptime, not hope for it. Certified: AWS DevOps Engineer – Professional | AWS Solutions Architect – Associate | HashiCorp Terraform Associate (003) I work best with teams that want infrastructure they can trust clean IaC, documented runbooks, and systems built to last. Available for long-term platform engineering partnerships, DevOps retainers, and project-based engagements. Message me and we'll spend 15 minutes figuring out whether I'm the right fit for your infrastructure.

Hey, I'm Serge — a DevOps engineer and Linux sysadmin with 16 years of hands-on experience. Top Rated Plus on Upwork, $70K+ earned, 100% Job Success Score across 24 contracts. My day-to-day involves leading DevOps work for US and Israeli companies — finance, government, tech. Through my employer, the rate is around $100–120/hr — that includes company overhead, account managers, and the usual agency markup. Here on Upwork you hire me directly. No middlemen, no account managers. That's why the rate is lower — not because the work is different. What I focus on most: **Kubernetes and container infrastructure** I've set up and migrated dozens of projects to Kubernetes — EKS, GKE, AKS, and on-prem. I handle the full stack: Helm-based deployments, Grafana + Loki for monitoring and logging, Terraform for infra as code. If your app is still running on Docker Compose and you're hitting limits, this is exactly what I do. **CI/CD pipelines** Setting up proper pipelines from scratch — GitLab CI, GitHub Actions, Helm. Dev/stage/prod environments with proper Git flow so your developers aren't blocking each other. **Cloud infrastructure — AWS, GCP, Azure** Terraform for everything that can be described as code. Multi-environment setups, VPC, networking, RDS, S3, load balancers, security groups. Migrations between accounts, between clouds, and from on-prem to cloud. **AI infrastructure** More recently I've been setting up GPU-based AI infrastructure — Ollama, vLLM, LiteLLM proxy. If you're deploying local LLMs or building AI-powered apps and need the infra side sorted, that's something I can help with too. **A few practical things:** - Up to 8 hours/day — I work focused, not just "clocked in" - You work directly with me throughout the project - I write documentation so your team can actually use what I build If you have a project in mind and want to talk through the scope first, I'm happy to do a short call. Just send a message. Serge ---
