Hi,

I’m working on a personal project and I need help setting up the infrastructure properly. Here’s what I’m trying to achieve:
• Observability using Grafana, Prometheus, and Loki
• Docker setup for the whole stack
• CI/CD pipelines:
• Deploy to production when main is updated (after tests pass)
• Deploy to staging when staging is updated
• Add Bull Board to monitor BullMQ queues
• Create encrypted PostgreSQL database backups to another server

The stack is: NestJS, PostgreSQL, Redis (2 instances: one for BullMQ and one for cache). The code is on GitHub and I plan to deploy everything to a VPS like OpenOcean (not using cloud providers like AWS or GCP).

Right now I’m running a single NestJS instance, but I’d like to move to a more solid, production-ready setup with monitoring and automation.

Skills: Docker, CI/CD, DevOps, Deployment Automation
