dVS — Video Management System (Mindhop)
The VMS backend I built for dotstream: multi-vendor camera ingest with PTZ control, FFmpeg/RTSP pipelines, WebRTC delivery, gevent-driven concurrency. Consumed by the dotstream operator UI.
Bash Operations Library
Production-grade infrastructure tooling: 550+ scripts, ~110,000 lines. Thematic modules for SSH and tunnel orchestration, security testing, systemd templating, OOM recovery, secrets management, Docker, sync, and cross-host automation across a 6+ Linux fleet. Hardlink-based deployment; single
logger.sh library at 1,580 lines.Personal & Research Projects

Hubitat Device Drivers
ESP8266 / ESP32, Midea AC, IR controllers, custom sensors (10+ production drivers).
Roomba Reverse Engineering
WiFi protocol analysis and custom SmartThings integration, documented in a long-running forum thread.
Technical Highlights
Custom UART Protocol
ESP32 + ATmega2560 dual-processor robot coordination with custom framing and error handling.
LiDAR Protocol Implementation
Reverse-engineered TEMS TemsInfo protocol from C# reference to a clean Python implementation.
Gevent Blocking Resolution
Identified and lifted a 30 s blocking call on a streaming path; final response time < 5 ms.
Legacy Code Refactoring
1000+ line monolithic smart-home front-end refactored into 20 cleanly-typed ES6 modules.
Async Device Monitoring at Scale
Thousands of field devices polled with adaptive batching; deployment scripts refuse to boot if
ulimit is insufficient and guide the operator.WebRTC / MediaMTX Streaming
Multi-vendor camera unification with WHEP / WHIP and HLS transcoding; ~200 ms glass-to-glass.
Multi-Hub Failover
Three-hub redundancy architecture for 24/7 IoT device reliability across the home lab.
NTCIP / SNMP Protocol Stack
Dynamic Message Sign control via SNMP v1 / v2c / v3 with per-vendor profiles and MIB-driven validation.
Matter Protocol Integration
Dual-command architecture — Hubitat plus Matter over WebSocket — for resilient home automation.
