Hi, I'm Chase!
Digital Systems | Infrastructure | RF Edge Systems
I build real-world systems that combine data, automation, and infrastructure.
From monitoring platforms and dashboards to full infrastructure environments, everything I create is designed to solve practical problems and scale.
- π Currently building system monitoring platforms & dashboards
- π₯οΈ Running a full homelab (Proxmox HA Cluster, Kubernetes, Docker)
- βοΈ Focused on infrastructure, automation, and observability
- π§ Ask me about K3s clusters, system monitoring, or homelab design

# π§ Cedβs NOC System
π **Portfolio Site:** https://chasedumphord.com
π **Live NOC Dashboard:** https://noc.chasedumphord.com
This repository represents a **live Network Operations Center (NOC) system**, not just a static portfolio.
It showcases:
* π **Cedβs NOC Dashboard** (real system monitoring)
* π§ **HomeLab Infrastructure** (HA virtualization, VLANs, services)
* βΈοΈ **K3s Cluster** (distributed compute)
* π‘ **APRS iGate (RF Edge System)**
---
# π Cedβs NOC Dashboard
A central visibility layer for all systems.
This dashboard includes real Grafana, Prometheus, and Blackbox Exporter monitoring for live HomeLab services.
---
## π What it shows:
* Infrastructure health
* Service availability
* Network segmentation
* RF edge system status
---
## π§ Why it matters:
This demonstrates:
* System monitoring mindset
* Operational visibility
* Real-world infrastructure awareness
* Ability to translate data into actionable insights
---
## πΌοΈ Live Dashboard Preview
### π Metrics Overview
### π₯οΈ Systems Overview

# π§ Featured System β Cedβs NOC (Network Operations Center)
A real-time monitoring and observability platform built on top of my homelab infrastructure.
---
## π What it demonstrates:
* Live system monitoring (services, nodes, edge systems)
* Infrastructure visibility across VLANs and clusters
* Service health tracking (latency, uptime, status)
* Real data ingestion (NOT simulated)
* Dashboard design for operational awareness
---
## βοΈ Monitoring Stack:
* Grafana (Visualization)
* Prometheus (Metrics collection)
* Blackbox Exporter (Service uptime & latency checks)
* Uptime Kuma (External monitoring layer)
π This is the **core system** that ties everything together.

# 𧱠Foundation β Cedβs Home Lab (Infrastructure + Monitoring)
Real-world environment used to simulate production systems and host services.
This is the backbone of Cedβs NOC β where all systems, services, and monitoring originate.
---
## βοΈ Core Infrastructure
* **Proxmox HA Cluster (High Availability Virtualization)**
* K3s Kubernetes cluster (Raspberry Pi - 12 nodes)
* TrueNAS storage system
* Docker / containerized workloads
---
## π Networking Layer
* VLAN segmentation
- Main Network
- IoT Network
- HomeLab Network (10.10.30.0/24)
- Guest Network
* Nginx Proxy Manager (external access layer)
* Cloudflare Tunnels (secure remote access)
---
## π Monitoring Stack (LIVE)
* Grafana (Dashboards)
* Prometheus (Metrics)
* Blackbox Exporter (Service Monitoring)
* Uptime Kuma (External Monitoring)
π The NOC dashboard is built directly on top of this environment.

# π‘ Edge System β APRS iGate (RF β Internet Gateway)
A real-world RF system that feeds live data into infrastructure.
---
## βοΈ System Components
* Raspberry Pi + Direwolf APRS TNC
* Audio chain tuning (critical for decode accuracy)
* APRS-IS integration
* Real beacon ingestion from handheld radios
π **Project:**
https://github.com/ced4568/ceds-aprs-igate
---
## π₯ Key Insight
This system bridges:
```text
RF radio signals β Raspberry Pi / Direwolf β APRS-IS β Digital Infrastructure
```
---
## π― Key Tuning Insight
* Target audio level: **~50β60**
* Too high β clipping / decode failure
* Too low β missed packets
This was tuned using:
* Direwolf audio level output
* Real beacon testing from handheld radios
