Need a Linux server set up, a site or email migrated, or a Docker app deployed with SSL? I'm a Linux system administrator and DevOps engineer. I set up, fix, migrate and automate Ubuntu and Debian servers, and hand over everything documented so you can run it without me. WHAT I CAN HELP WITH • Server setup and deployment: VPS, AWS EC2, domains, SSL, Nginx reverse proxy, Docker Compose • Migrations: server to server, websites, DNS and email (Google Workspace, Zoho, Microsoft) with minimal downtime • Troubleshooting: 502/500 errors, failing containers, full disks, high CPU or memory, expired SSL, broken DNS, failed cron jobs • Mail servers and deliverability: Postfix, SMTP, SPF, DKIM, DMARC, spam and blacklist fixes • Private VPN for teams and remote access (OpenVPN) • Backups and automation: Bash scripts, cron, systemd, scheduled backups, simple CI/CD • Open-source apps on your own server: n8n, Nextcloud, Overleaf, Taiga and more HOW I WORK • I take a backup or snapshot before changing anything, so there is always a way back. • I ask only for the access the task needs, and tell you what to revoke when I'm done. • I finish the job: a migration ends with the new server working and the old one safe to switch off. • Everything comes with a short written handover of what was changed and how to maintain it. • Happy to sign an NDA. STACK Linux: Ubuntu, Debian, systemd, cron, Bash Containers: Docker, Docker Compose Web: Nginx, reverse proxy, SSL / Let's Encrypt Network: DNS, Cloudflare, OpenVPN, SSH, firewall (UFW, iptables) Cloud: AWS EC2, S3, IAM, VPC Mail: Postfix, SMTP, SPF, DKIM, DMARC Automation: CI/CD, Git, backups Send me what you are working with, what is not working, and any error message. I will reply with a fixed price or a clear estimate.
