Reliable DevOps Engineer Needed

I’m looking for an experienced DevOps / Backend Engineer to set up and configure a self-hosted Supabase instance on my Ubuntu VPS. Docker is already installed, but it should be verified and properly configured. The goal is a secure, production-ready Supabase stack running locally (Postgres, Auth, REST, Realtime, Storage, Kong Gateway, and optional Studio), behind an HTTPS reverse proxy with automatic backups and full documentation. Scope of Work Docker & Environment Setup Verify existing Docker installation (version, permissions, network stability). Create dedicated Docker network (supabase_net). Prepare directory structure under /opt/supabase/. Supabase Stack Installation Deploy Supabase components using Docker Compose: Postgres GoTrue (Auth) PostgREST (REST API) Realtime Storage API Kong Gateway (Optional) Supabase Studio Configure .env and docker-compose.yml following best practices: No public database ports. All services communicate over internal Docker network. Security & Networking Set up Nginx reverse proxy for HTTPS with Let’s Encrypt certificates. Configure UFW firewall (only ports 22, 80, 443 open). Add security headers and enforce HTTPS redirects. Keep all credentials and secrets outside version control. Backups & Monitoring Implement automated daily PostgreSQL backups (with 30-day retention). Include a tested restore script. Add basic monitoring and health checks (Docker health, HTTP status). (Optional) S3-compatible offsite backup upload. Testing & Validation Verify user sign-up, login, and password reset via GoTrue (SMTP). Confirm REST endpoints respond via HTTPS. Validate Storage uploads/downloads. Test Realtime subscriptions. Run at least 3 negative RLS access tests.

Required Skills Docker & Docker Compose (production environments) Supabase or similar stacks (Postgres, GoTrue, Kong, Realtime) Linux server administration (Ubuntu) Nginx + Let’s Encrypt TLS setup Bash scripting (for backup/restore) PostgreSQL and basic SQL/RLS understanding Additional Notes Docker is already running but needs verification. Domain and DNS are fully configured. No Supabase cloud integration — this must be 100% self-hosted. Open to small improvements if you can make the setup more robust or secure. ⚠️ Reliability Disclaimer Only apply if you agree to the fixed budget and milestone structure.
