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.

• 🚀 Currently building system monitoring platforms & dashboards
• 🖥️ Running a full homelab (Proxmox HA Cluster, Kubernetes, Docker)
• ⚙️ Focused on infrastructure, automation, and observability
• 🧠 Ask me about K3s clusters, system monitoring, or homelab design

🧠 Ced’s NOC System

👉 Portfolio Site: https://chasedumphord.com
👉 Live NOC Dashboard: https://noc.chasedumphord.com

This repository represents a live Network Operations Center (NOC) system, not just a static portfolio.

It showcases:

• 📊 Ced’s NOC Dashboard (real system monitoring)
• 🧠 HomeLab Infrastructure (HA virtualization, VLANs, services)
• ☸️ K3s Cluster (distributed compute)
• 📡 APRS iGate (RF Edge System)

📊 Ced’s NOC Dashboard

A central visibility layer for all systems.

This dashboard includes real Grafana, Prometheus, and Blackbox Exporter monitoring for live HomeLab services.

---

🔍 What it shows:

• Infrastructure health
• Service availability
• Network segmentation
• RF edge system status

---

🧠 Why it matters:

This demonstrates:

• System monitoring mindset
• Operational visibility
• Real-world infrastructure awareness
• Ability to translate data into actionable insights

🔴 Live System Status

---

🧠 Featured System — Ced’s NOC (Network Operations Center)

A real-time monitoring and observability platform built on top of my homelab infrastructure.

---

🔍 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

---

⚙️ Monitoring Stack:

• Grafana (Visualization)
• Prometheus (Metrics collection)
• Blackbox Exporter (Service uptime & latency checks)
• Uptime Kuma (External monitoring layer)

👉 This is the core system that ties everything together.

---

🧱 Foundation — Ced’s Home Lab (Infrastructure + Monitoring)

Real-world environment used to simulate production systems and host services.

This is the backbone of Ced’s NOC — where all systems, services, and monitoring originate.

---

⚙️ Core Infrastructure

• Proxmox HA Cluster (High Availability Virtualization)
• K3s Kubernetes cluster (Raspberry Pi - 12 nodes)
• TrueNAS storage system
• Docker / containerized workloads

---

🌐 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)

---

📊 Monitoring Stack (LIVE)

• Grafana (Dashboards)
• Prometheus (Metrics)
• Blackbox Exporter (Service Monitoring)
• Uptime Kuma (External Monitoring)

👉 The NOC dashboard is built directly on top of this environment.

📡 Edge System — APRS iGate (RF → Internet Gateway)

A real-world RF system that feeds live data into infrastructure.

---

⚙️ System Components

• Raspberry Pi + Direwolf APRS TNC
• Audio chain tuning (critical for decode accuracy)
• APRS-IS integration
• Real beacon ingestion from handheld radios

🔗 Project: https://github.com/ced4568/ceds-aprs-igate

---

🔥 Key Insight

This system bridges:

RF radio signals → Raspberry Pi / Direwolf → APRS-IS → Digital Infrastructure

---

🎯 Key Tuning Insight

• Target audio level: ~50–60
• Too high → clipping / decode failure
• Too low → missed packets

This was tuned using:

• Direwolf audio level output
• Real beacon testing from handheld radios

---
