Linux / DevOps Engineer Needed - Build Secure AI Development & Staging Environment

# Linux / DevOps Engineer Needed - Build Secure AI Development & Staging Environment I am looking for an experienced Linux / DevOps engineer to configure and harden a newly provisioned Ubuntu VPS that will serve as a dedicated Development and Staging environment for software development, workflow automation, and AI-assisted development. This is a fresh server build. No production applications currently exist on the server. The objective is to create a secure, documented, maintainable environment that closely mirrors an existing Production environment while remaining isolated from Production workloads. The environment must support: * Docker * Docker Compose * Self-hosted n8n * PostgreSQL * GitHub * Claude Code * Future workflow development and testing Deliverables include: * Server hardening and security configuration * Docker installation and configuration * Self-hosted n8n deployment and configuration * PostgreSQL development environment * GitHub integration * Claude Code installation and validation * SSL and reverse proxy configuration * Backup and recovery procedures * Development-to-Production promotion strategy * Complete documentation and knowledge transfer This project is focused on infrastructure, security, configuration, and documentation. I am not looking for application development at this stage. A detailed BRD is attached and should be reviewed before submitting a proposal. Please begin your proposal with: "Development Environment" and include: 1. Relevant Linux administration experience 2. Docker experience 3. n8n experience 4. PostgreSQL experience 5. Experience securing public-facing servers 6. Examples of similar work 7.
