Hire the Best Rackspace Cloud Servers Developers

I build and run Production Infrastructure on AWS, GCP, Azure and on-prem. Most of my work the last few years has been Kubernetes (EKS, GKE, AKS, and bare metal RKE2 with Rancher) and getting that infrastructure through compliance audits: HIPAA, SOC 2, PCI DSS, NIST 800-53. 10+ years in DevOps. Top Rated Plus, 100% Job Success. 𝙎𝙤𝙢𝙚 𝙧𝙚𝙘𝙚𝙣𝙩 𝙥𝙧𝙤𝙟𝙚𝙘𝙩𝙨 𝙩𝙤 𝙜𝙞𝙫𝙚 𝙮𝙤𝙪 𝙖𝙣 𝙞𝙙𝙚𝙖 𝙤𝙛 𝙬𝙝𝙖𝙩 𝙄 𝙖𝙘𝙩𝙪𝙖𝙡𝙡𝙮 𝙙𝙤: Built an on-prem RKE2 cluster from scratch for a company preparing for SOC 2 and HIPAA. Rancher for management, Cilium with WireGuard for encrypted pod traffic, GPU nodes for their ML workloads, Longhorn for storage, Velero for backups, ArgoCD for deployments. Also enforced SSO through Entra ID on every cluster and SSH access point because their auditors required it. Took a healthcare data platform through HIPAA hardening on AWS. ECS Fargate, Aurora PostgreSQL, private subnets, TLS everywhere, proper secrets handling. Phase one was making it work, phase two was making it pass an audit. Different skill sets, I do both. Modernized AWS infrastructure for a holding group running four brands. Moved everything to ECS Fargate and Aurora Multi-AZ, set up blue-green deployments, CloudFront in front. Midway through we found a security breach in their GitHub org and I handled the full remediation across every repo. Fixed a production Aurora MySQL performance problem that had their app timing out during peak hours. Root cause was tmp table spill to disk. Tuned it, added a reader, no downtime. I also do a lot of unglamorous work that keeps things running: CI/CD pipelines (GitHub Actions, GitLab CI, ArgoCD), Terraform for everything, monitoring with Prometheus and Grafana, cost cleanup, VPN and networking issues, database migrations. Industries I know well: Healthcare (HIPAA is second nature at this point), Fintech and Payments (PCI DSS), and B2B SaaS. 𝙒𝙝𝙖𝙩 𝙮𝙤𝙪 𝙜𝙚𝙩 𝙬𝙤𝙧𝙠𝙞𝙣𝙜 𝙬𝙞𝙩𝙝 𝙢𝙚: Infrastructure that is written down in code, documented, and reproducible. I answer messages fast and I will tell you upfront if something is a bad idea or if I am not the right person for it. Send me your project details and current setup. I will give you an honest read on scope and effort before you spend anything.

Your infrastructure breaks at 2 AM. Your deploys take 45 minutes. Your AWS bill climbed 40% and nobody can explain why. I fix all three - and I've done it 100+ times on this platform. Former SRE Lead at Yellow AI (100M+ users, AWS + on-prem). Now I run Skybyte, a DevOps and cloud consulting practice focused on startups and mid-market teams that need senior infrastructure work without the senior hire. What 61+ Upwork jobs and a 100% Job Success Score actually look like: Cloud cost optimization - cut AWS/Azure/GCP spend by 40-60% through right-sizing, Reserved Instances, spot fleets, and architecture cleanup. Not guesswork; I run the cost audit, build the dashboard, and hand you the savings. Kubernetes migration and management - moved production workloads to EKS, AKS, and self-managed clusters on Hetzner. Helm charts, ArgoCD GitOps, zero-downtime cutovers. I've handled clusters running 200+ pods and clusters running 6. CI/CD pipeline engineering - GitHub Actions, GitLab CI, Azure DevOps Pipelines, Bitbucket Pipelines. Took teams from 45-minute manual deploys to sub-5-minute automated releases with rollback built in. Infrastructure as Code with Terraform - full AWS, Azure, and GCP environments defined in Terraform modules. State management, drift detection, and PR-based infrastructure reviews that your team can maintain without me. DevSecOps and compliance - SOC 2 infrastructure from scratch, cloud security audits, Cloudflare WAF and DDoS protection, network security architecture, and DPDP-aligned data handling. I've built the controls and written the documentation auditors actually accept. Monitoring, observability, and SRE - Prometheus, Grafana, OpenTelemetry, Datadog, PagerDuty. Full observability stacks that catch failures before your users file tickets. I set up SLOs, runbooks, and on-call workflows. Beyond core DevOps - SSO/SAML integration, n8n workflow automation, MLOps pipelines, Docker deployments on bare metal and VPS, GCP Cloud Run serverless, and technical documentation your team won't ignore. I work best with funded startups burning money on cloud, engineering teams stuck in deployment hell, and companies scaling past the point where one developer can manage the infrastructure part-time. Stack: AWS (EKS, EC2, Lambda, RDS, S3) · Azure (AKS, DevOps, AD) · GCP (GKE, Cloud Run) · Kubernetes · Helm · Terraform · Docker · GitHub Actions · GitLab CI · ArgoCD · Prometheus · Grafana · OpenTelemetry · Datadog · Cloudflare · n8n Not a "set it up and disappear" contractor. I document everything, train your team, and build systems designed to run without me and scale.
