Client Project – Multi-VM Production Infrastructure (Hyper-V, Docker, Nginx, PostgreSQL) Freelance | Remote
-Designed and implemented a multi-environment infrastructure (Production, Staging, QA) on Windows Server 2022 with Hyper-V, hosting multiple Linux VMs (Ubuntu).
-Architected secure VM networking using Hyper-V NAT, static internal IP planning, and controlled external port exposure.
-Implemented Docker-based application deployments for:
o Django backend services
o Next.js / React frontend services
o PostgreSQL databases (containerized and VM-based)
-Built a central reverse proxy on Windows using Nginx, enabling:
o Multiple subdomains routed to different internal VMs
o Single public IP serving multiple environments
o HTTP → HTTPS redirection
-Implemented HTTPS for all environments using Let’s Encrypt (win-acme) with:
o Automated certificate issuance
o Scheduled auto-renewal via Windows Task Scheduler
o Secure TLS configuration
-Configured PostgreSQL (v16+) on dedicated database VMs:
o External access via controlled NAT forwarding
o Secure role-based authentication
o Network-restricted pg_hba.conf rules
-Set up secure FTP (vsftpd) on multiple VMs:
o Unique external ports per VM
o Non-overlapping passive port ranges
o Firewall-restricted access
-Implemented security best practices:
o Isolated environments (Prod / Staging / QA)
o Port minimization and structured port allocation
o Firewall (UFW) rules per VM
o Reverse-proxy-based exposure instead of direct VM access
-Created deployment documentation and port-mapping standards to support future VM scalability.
-Performed zero-downtime container updates, image replacement, and troubleshooting
