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.
