Software engineer in Nashville, TN, writing C#/.NET, C++, and Python. I mostly build small, focused libraries and the tools on top of them.

Right now I'm working on voice agents that use a real phone line: SIP telephony, speech detection, echo cancellation, and the pieces that let an AI agent place and answer calls.

• pbx-voice: a daemon that places phone calls for AI agents through your own SIP PBX. It handles wake-up alarms, spoken messages, and short goal-driven conversations, and agents request calls over MCP.
• SipBotLib: a headless SIP library for .NET, built on SIPSorcery, with a sipbot CLI for agents. It can register, answer, dial, transfer, send DTMF, and stream PCM audio.
• SipBotOpen: a voice agent that answers incoming calls as a PBX extension. It runs speech-to-text and text-to-speech locally and uses an LLM with tool calling.
• MinimalSileroVad: voice activity detection and speech segmentation for .NET, using the Silero VAD model (V4 and V5) on ONNX Runtime. It works with 8 kHz and 16 kHz audio.
• clean-speech: a Linux microphone cleanup daemon. It cancels echo from system playback, suppresses noise, gates on speech, and publishes the result as a virtual microphone.
• MinimalDiarization: speaker diarization for .NET on ONNX Runtime, with experimental preprocessing for picking out voice commands in noisy rooms.
• MinimalVoiceAgent: a minimal voice agent with tool calling, local speech-to-text and text-to-speech, and Grok over the xAI API.

• MinimalTextClassifier: a binary text classifier for .NET on ONNX Runtime, with Python scripts for fine-tuning DeBERTa on your own data.
• youtube_skip_button_fine_tuned_yolo: a fine-tuned YOLO11 model that detects YouTube "Skip ad" buttons, plus the data collection and training scripts.

Models are published on Hugging Face.

• XMapLib: maps Xbox controller input to keyboard and mouse input on Windows, with rebindable keys and adjustable mouse sensitivity.
• impcool_sol: a thread pool for long-running tasks that uses immutability to keep the implementation simple.
• StreamToActionTranslator: the XMapLib keyboard core as a C++23 CMake library that turns an input stream into function calls, with unit tests.
