I migrate, harden, and run hybrid infrastructure across AWS, VMware, and Proxmox so you get one architect for both your cloud and your on-prem stack instead of stitching together three specialists. Whether you're moving on-prem workloads to AWS, building a Proxmox or VMware cluster, recovering a broken Linux server, or automating deployments with Ansible and CI/CD, I've done it across 85 completed jobs at a 100% Job Success score. 13+ years of hands-on enterprise infrastructure experience, AWS-certified (Solutions Architect, SysOps, Developer) and KCNA, with real production work behind every claim below. Cloud & migration On-prem ↔ AWS migrations (MGN/DRS), EC2, ECS/Fargate, Lightsail, CloudFront, NGINX, SSL/certificate setup, and AWS backup configuration. I've moved live workloads both directions AWS to on-prem and Dell PowerEdge to consolidated micro-servers without losing data or uptime. Virtualization Proxmox (installs, v6→v8 upgrades, cluster setup, VM/VMDK exports from AMI) and VMware (vCenter/ESXi cluster setup, vSphere, VMDK migrations). This is repeat work for me, not a side skill. Disaster recovery & resilience Tested DR with real RTO/RPO targets, warm-standby and pilot-light patterns, and backup strategies that actually restore verified, not assumed. DevOps & automation Ansible-first configuration automation, Docker and Docker Swarm, Jenkins CI/CD pipelines, and containerized deployments. I automate the repeatable so your team stops doing it by hand. Linux & hardening Server hardening, security baselines, performance tuning, hosting stacks (Plesk, cPanel), and monitoring with DataDog across Ubuntu, RHEL/CentOS, and SUSE. What clients consistently say: clear communication, reliable delivery, and solving the actual problem instead of the surface symptom. Send me a short description of your environment and what you're trying to achieve. I'll reply with a straight assessment and an honest recommendation on whether I'm the right fit usually within a few hours.
