A self-contained, bare-metal platform running 24/7 without dependency on managed cloud. From host hardening and edge gateway to container orchestration, data persistence and observability. Built for maintainability, security and uptime in industrial environments.
Core Metrics
50+ Services · 99.9% Uptime · Single Maintainer · 100% Dockerized · Zero Cloud Vendor Lock-in
Architecture Overview
Figure 1: End-to-end traffic flow, service isolation, and secure remote access.
High-Level Flow:
`Internet → Edge Gateway [Traefik / Nginx + Let's Encrypt] → Docker Host [Hardened Ubuntu] → App / Data / Observability → Secure Admin [WireGuard VPN]`
Core Infrastructure Modules
The platform is structured into six independent yet integrated layers, each designed for resilience and operational clarity.
1. ⚡ Hardened Linux Host
A secure, minimal Ubuntu foundation with system hardening, automated security patches, and custom Python automation for routine maintenance. This is the bedrock of the entire platform.
Stack: Ubuntu Server · System Hardening · Python · Bash Automation
2. 🔐 Edge Proxy & Zero-Trust Access
All external traffic enters through a secure edge layer. Traefik acts as the dynamic reverse proxy with automatic Let’s Encrypt SSL termination, while WireGuard provides encrypted VPN tunnels for remote engineering access.

Stack: Traefik · Nginx · WireGuard VPN · Let's Encrypt · Docker
3. 🧩 Containerized Application Hosting
A multi-container environment running modern and legacy web applications side-by-side. This layer hosts React frontends, Node.js APIs, Laravel/PHP backends, and PostgreSQL databases — all orchestrated via Docker Compose with zero-downtime updates.
Stack: Docker · Node.js · React · Laravel · PostgreSQL · LAMP
4. 📊 Data & System Observability
Centralised monitoring and logging stack providing real-time visibility into host metrics, container health, application performance, and business KPIs. Custom Grafana dashboards correlate system events with application logs for rapid troubleshooting.

Stack: PostgreSQL · Grafana · Prometheus · Loki · Web Analytics
5. ☁️ Sovereign Collaboration Suite
A fully self-hosted alternative to corporate cloud services. This module provides secure file sharing (Nextcloud), decentralised team messaging (Matrix), enterprise email (Postfix/Dovecot), and isolated remote desktops (Kasm Workspaces) — ensuring data sovereignty and privacy compliance.
Stack: Nextcloud · Matrix (Element) · Mail Server (SMTP/IMAP) · Kasm Workspaces
6. 📡 IoT & Live Data Edge
The direct link to your “RF Communications” and “Industrial Integration” expertise. This layer handles real-time telemetry from field devices (sensors, LoRa gateways, CCTV) and streams live data to web-based dashboards using WebSockets and low-latency protocols.
Stack: Live Streaming · WebSockets · Real-time Dashboards · MQTT · Edge Processing
