# I build systems that connect hardware, networks, and operations.

Chase Dumphord — infrastructure builder running Proxmox, K3s, TrueNAS, and APRS RF edge systems out of Oxford, MS. I build things that actually work, then document how they work.

## Hands-on systems builder with a digital infrastructure mindset

I'm a technical professional focused on digital systems, infrastructure, networking, automation, and hands-on system integration. I build things that are practical, reliable, and well-documented — from homelab services and live dashboards to Raspberry Pi deployments, APRS iGates, and complex troubleshooting workflows.

My background blends field engineering, industrial technology, and infrastructure problem solving. Increasingly I'm integrating AI tooling — using LLMs for system documentation, automated diagnostics, and workflow acceleration — as part of how modern infrastructure gets built and maintained.

### Core Focus Areas

- Digital systems and infrastructure engineering
- Linux systems and service management
- Networking, VLANs, failover, and connectivity troubleshooting
- Raspberry Pi and edge-device deployments
- AI-assisted automation, documentation, and diagnostic workflows
- Documentation, process building, and reproducible project design

// projects

## Infrastructure & Systems Projects

Built on real systems. Not demos, not tutorials — running infrastructure.

### Ced's HomeLab Infrastructure

Flagship

Infrastructure • Networking • Virtualization • Monitoring • Self-Hosting

Full homelab environment built for real network segmentation, service hosting, and architecture documentation.

- Proxmox VE virtualization platform
- VLAN segmentation via UniFi (Main / IoT / HomeLab / Guest)
- Self-hosted services behind Nginx Proxy Manager + Cloudflare Tunnels
- Uptime Kuma + Grafana monitoring stack

View on GitHub →

### K3s Kubernetes Cluster

Infrastructure

Kubernetes • Containers • Linux • Automation

12-node K3s cluster on Raspberry Pi built to simulate distributed infrastructure and container orchestration at scale.

- Multi-node cluster setup and management
- Containerized workload deployment
- Infrastructure automation via manifest-driven configuration

View on GitHub →

### APRS iGate System

Edge System

RF • Linux • Raspberry Pi • APRS-IS • Edge Systems

Operational dual-node RF-to-internet gateway. Decodes real beacon packets and uplinks live to aprs.fi.

- Direwolf APRS TNC with tuned audio chain (target: 50–60 level)
- APRS-IS uplink verified on aprs.fi
- HomeLab WiFi + mobile hotspot failover
- Mobile build with ETH-USB-HUB-BOX expansion

## Ced's NOC Vision

Staged monitoring and systems-visibility platform built on real infrastructure.

✅ Live

### Portfolio NOC

JSON-driven dashboard showing real inventory, online/offline checks, service labels, latency, and last-check timestamps.

⚙️ Next

### Automated Data Updates

Scheduled local scripts will auto-refresh system status and push dashboard-ready JSON on a cron interval — no manual updates.

📈 Future

### Grafana + Prometheus

Full observability stack for Proxmox, TrueNAS, K3s, Raspberry Pi nodes, Uptime Kuma, and APRS edge systems with real-time metrics ingestion.

## Technical experience that bridges field work and digital systems

### What I Bring

- Industrial and field-service technical background — hands-on problem solving under real constraints
- Linux systems administration — service management, troubleshooting, automation
- Networking depth — VLANs, DNS, reverse proxy, firewall config, failover design
- Infrastructure-as-documentation mindset — everything I build gets written up
- Homelab → production thinking — I build lab environments that mirror real-world system design

### Target Roles

- Systems / Infrastructure Engineer
- NOC Technician / Network Operations
- Linux Systems Administrator
- Technical Operations / IT Infrastructure
- Edge Systems / Field Technical Roles

Currently positioning around digital systems, infrastructure, and technical operations — especially roles where hands-on problem solving and system integration matter more than certifications.

## Technical, curious, and always building

Outside of work I'm into electronics, self-hosting, coding, drones, ham radio, and hands-on projects that force me to learn something real. Ball pythons and dogs round out the home lab. That curiosity carries directly into how I build and document systems.
