🏛️ Networking & IoT Projects Portfolio

1. OpenWrt Kernel NFS Server Manager

Native LuCI web application and UCI configuration engine controlling wire-speed Linux kernel nfsd daemons directly on OpenWrt routers with multi-client access control.

2. OpenWrt Attended Sysupgrade (ASU) Image Builder

Automated on-demand custom kernel and SquashFS firmware compilation pipeline utilizing FastAPI, RQ workers, and isolated OpenWrt ImageBuilder containers.

3. OpenWRT Blackhole Webserver & Honeypot

Ultra-lightweight edge service serving zero-byte HTTP 200 responses to hostile port scans and web scrapers, mitigating perimeter noise without resource overhead.

4. OpenThread Border Router Telemetry Poller

802.15.4 low-power wireless mesh network polling daemon extracting node neighbor tables, parent RSSI metrics, and streaming telemetry to MQTT and Grafana.

5. Dual-Band ADS-B & UAT Aviation SDR Telemetry Pipeline

Demodulating 1090MHz Mode S and 978MHz UAT flight telemetry using RTL-SDR hardware, WebGL aircraft radar, and multi-network feeder multiplexing.

6. SDR & RF Telemetry Exploration

Software-Defined Radio research capturing municipal, weather satellite, and ISM band radio frequencies with GNU Radio flowgraphs and automated waterfall recording.

7. Layer 2 Virtualization & Non-NAT IPAM

High-density Docker container network architecture using Macvlan and IPvlan driver bridges to eliminate NAT port mapping bottlenecks and provide routable LAN IPs.
