DevOps and Linux engineer with 4+ years running production infrastructure for businesses that cannot afford downtime. 100+ projects delivered on Upwork at a 96% success rate, currently managing systems that handle millions of requests a day. Most clients reach out for one of three reasons. Something broke and they need it fixed fast. They are scaling and their setup will not hold. Or they want someone to review their cloud and tell them honestly what is wrong. I handle all three, find the root cause, fix it properly, and document everything so your team can maintain it. ☁️ 𝗖𝗹𝗼𝘂𝗱 & 𝗗𝗲𝘃𝗢𝗽𝘀 AWS, Azure, GCP, Oracle Cloud, DigitalOcean, Hetzner.

Struggling with unreliable infrastructure, VMware licensing costs, or a stalled cloud migration? I'm a DevOps & Cloud Engineer who builds and stabilizes production environments across AWS, Azure, Proxmox, and Ceph — with a focus on uptime and automation. Most DevOps engineers specialize in either cloud or on-prem infrastructure. I do both: I've run production Proxmox VE clusters with Ceph storage alongside AWS, Azure, and GCP deployments, and I handle VMware-to-Proxmox migrations end-to-end — a combination few freelancers on Upwork cover with hands-on production experience. Here's how I typically help clients: ✔ Design and deploy cloud infrastructure on AWS, Azure, or GCP ✔ Build and troubleshoot Proxmox clusters, including VMware-to-Proxmox migrations ✔ Optimize and recover Ceph storage clusters ✔ Set up Docker and Kubernetes environments with CI/CD pipelines ✔ Implement monitoring with Zabbix and Grafana ✔ Plan and test backup and disaster recovery strategies ✔ Secure infrastructure with VPNs, firewalls, and Zero Trust practices Top Rated Plus on Upwork with a 4.98 rating across 51 completed jobs and over 2,870 hours worked.
