Hey, I'm
Clancy Dennis
I'm the one who
I'm endlessly curious about how people work — the lungs, the habits, the messy human bits — and stubborn enough to keep building until the technology actually fits them. That curiosity has dragged me from Sydney to France to a Bavarian mountain village to California, and it is why I still get a kick out of shipping something on a Sunday just to see if it flies.
These days I build AI at Stanford Healthcare. The rest of the time I make things — worms lobbing artillery at language models, a ukulele game that tricks you into practising, a small family of agents called Otto — and run experiments on gluten-free bread in between. It's all the same instinct: poke at it, measure it, make it better.
Three disciplines that don't usually meet in one person.
Everything below this line is evidence of what happens when they do.

Scaling Intelligence
What I do at Stanford Healthcare: getting generative AI into a hospital safely, and the deterministic algorithms that taught me how.
LLMs in Healthcare: Automating Clinical Workflows
Senior Data Engineer @ Stanford Healthcare
Large Language Models are transforming healthcare by automating documentation, enabling natural language interfaces to clinical data, and reducing physician burnout. I architect production-grade LLM systems that bring generative AI safely into hospital environments—from AI scribes that auto-generate clinical notes to intelligent EHR assistants that let clinicians query patient records conversationally.
ChatEHR: Medical Chatbot
Privacy-preserving GenAI platform embedded in Epic EHR. Clinicians query patient records via natural language, reducing chart review time.
AI Scribes & Automated Notes
Real-time transcription systems that generate SOAP notes, treatment plans, and clinical summaries—freeing physicians to focus on patient care.
Workflow Automation
LLM-powered pipelines for prior authorizations, referral letters, patient communication, and administrative task automation.

Foundational Algorithms (The Logic Before The AI)
My work in Generative AI is built upon over two decades of architecting deterministic, life-critical therapy algorithms. This deep understanding of "Medical Logic" ensures my AI solutions are safe, grounded, and clinically valid.

Claude Commander
An autonomous AI orchestration system that ships real work through Plan → Build → Verify pipelines. A thin Rust runner that turns Claude Code into a repeatable, autonomous pipeline—without inventing a new agent framework.

Edge AI & Embedded Systems
aRVi — RV AI Kiosk
A touch-first Rust and Tauri control system that runs an off-grid RV from a single Orange Pi RK3588. One kiosk surfaces battery management, solar charge control, vehicle diagnostics, GPS, LTE messaging, and live camera feeds—with a voice-driven on-board assistant that can switch real loads through relay channels guarded by hard interlocks in Rust.
Built to survive being unattended: six independent recovery layers, from webview restart through the SoC hardware watchdog, plus fail-safe actuation rules that refuse heavy loads when battery state-of-charge is low, unknown, or stale.

Things I Make
The nights-and-weekends builds — the ones that start as “I wonder if that would work” and end up live on the internet because it turns out it does. Most are the Otti apps; all of them are me trying an idea out on real users, usually myself.
Wormdrop Battleground
3D worm artillery, played against LLMs.
A Three.js battlefield with permanently destructible terrain, where every rival worm is an LLM agent with its own persona, memory and trash talk.

UkeJam
Guitar Hero, but it actually teaches you the ukulele.
Chords scroll toward you and you play them for real. The game is the lesson — the fun is the thing that keeps you practising long enough to get good.

A Reddit where every user is an AI.
LLM instances post, argue, upvote and derail each other's threads. Equal parts research sandbox and spectator sport.
