Selected projects

• Clip Portal —A search over 300 public-domain films from the Prelinger collection, 66 hours, where each result is a frame at a second and clicking it seeks the player there. Pick clips into a set and an Evaluate page says what you would be licensing: runtime, decades, narrated or silent, near-duplicate pairs, a stratified sample, a manifest. The same search answers agents through three MCP tools, and a retrieval eval over 100 hand-written queries scores every path the site serves.
• Receipts —An investigation agent for Honeycomb that works a scripted incident in a real Honeycomb environment over the hosted MCP and has to cite the query and rows behind every claim. An eval harness with injected faults and known ground truth grades it on whether the answer was right, not on which tools it called.
• Agent Blue —An operations platform I built alone. A conservation nonprofit in Alaska runs their day to day on it, along with a handful of other client orgs. Chat agent on one side, a drafting API on the other, and a fact checker between the output and the person reading it.
• Earshot —One Kotlin core drives speech recognition on both iOS and Android. Whisper through WhisperKit on iOS, ONNX Runtime on Android. No audio leaves the phone.
• Pencil Count —A six-stage funnel that reads handwritten write-in votes off scanned ballot images using a 12B vision model running locally, and reconciles the tally against the official count.
• Sitewinder —An Android app that composes Whisper ASR, MiniLM embeddings, and Gemma 3 1B entirely on device, so you can ask questions about your own video library with the radio off.
• SigPocket —Ten years of observability work compressed into the screen you actually have on you when something pages. A mobile client for SigNoz, built because I wanted it.
