PROFESSIONAL EXPERIENCE

DevOps & System Architect (Project Work)

R7Learn (Education platform) | 2024 – now
GitHub: github.com/VLADos-IT/r7learn-platform

Development and support of a full-featured LMS platform with service-oriented architecture.

  • Architecture: Designed a distributed system: Frontend (Vite), Backend API (.NET), 3 services (Python/FastAPI). All services are hidden behind an internal Nginx and accessible only via VPN gateway.
  • Infrastructure: Full containerization of all system components using Docker Compose.
  • Automation (IaC): Wrote Bash scripts for deployment, backup rotation, and system recovery.
  • Observability: Implemented Prometheus + Grafana for metrics (Node, Docker, Nginx) and Loki for logs. Configured Blackbox Exporter for endpoint availability checks.
  • Security: Implemented a scheme with an external SSL terminator and internal traffic proxying via WireGuard tunnel.

Infrastructure Engineer (Self-hosted / Home Lab)

Project xorg.su (HomeLab / Distributed Infrastructure) | 2023 – Present
Design and administration of private cloud infrastructure based on multiple geographically distributed VDS.
Minimal visual architecture: Architecture

  • Network Topology: Built a Mesh network (WireGuard) with a central gateway providing a single entry point and traffic routing to private servers.
  • Services: Administration of Mailcow mail cluster (SMTP/IMAP/DKIM) and backup Relay server based on Postfix. Support for Forgejo Git service, Nextcloud cloud storage (PHP-FPM, Redis), and monitoring stack in Docker containers.
  • Proxy & Security: Configured Nginx as Reverse Proxy to route requests to internal IPs via VPN tunnels.
  • Observability: Centralized log collection (Promtail -> Loki) and metrics (Node Exporter -> Prometheus) from all nodes. Visualization in Grafana.
  • Hardening: Full closure of direct ports, SSH via Yubikey keys, automatic SSL certificate updates (Certbot).
