Proof Engine A Rust game engine where every frame on screen comes from real math: galaxies, attractors, fields.	tokio-prompt-orchestrator A bounded Tokio pipeline in front of your LLM: dedup, circuit breaker, dead-letter queue.
Hallucination highlighter Find the words your model was not sure about, and what it almost said instead.	Prompt Observatory Watch an LLM reply arrive chunk by chunk, see where it paused, know the cost before you send.
Every-Other-Token Sits on an LLM token stream, rewrites every other token, shows how sure the model was.	HelixRouter Adaptive async compute router for Tokio with a live dashboard and a learned routing policy.
SRFM Lab Price paths drawn as worldlines: every bar tested against a light cone.	Special Relativity in Finance A C++20 library that gives each OHLCV bar a price velocity, a Lorentz factor and a spacetime label.
LARSA A DQN ensemble trading one-second BTC order-book data with DeepSeek news sentiment in its state.	fin-primitives Exact-decimal market data types, indicators and position risk for Rust.

About

I build Rust tools for LLMs and markets, single-header C++ libraries, generative graphics, and iPhone apps. Most of it ships as something you can install and run today.

Moved here from GitHub (September 2026). Everything below is the current home of each project.

LLM tools (Rust)

Every-Other-Token (watch and rewrite an LLM's token stream live) · tokio-prompt-orchestrator (async pipeline for LLM prompts at scale) · llm-cpp (26 single-header C++ libraries for LLM features) · llm-cost-dashboard (terminal dashboard for LLM spend) · llm-bench (latency, throughput and cost across OpenAI and Anthropic) · HelixRouter (adaptive async compute router for Tokio) · llm_affector (a second LLM call that checks the first) · corescout (remembers how your machine and your AI work together) · prompt-observatory · tokenviz · llm-wasm · full catalogue

Markets and quant

fin-primitives (exact-decimal market data types and indicators) · fin-stream (real-time multi-venue tick pipeline) · crypto-orderbook (live, correctly sequenced Binance order book) · srfm-lab · Special-Relativity-in-Financial-Modeling · Reddit-Options-Trader-ROT · FinRL_DeepSeek_Crypto_Trading · LLMTokenStreamQuantEngine

Graphics, sound and games

geodesic-wallpaper (live geodesics on curved surfaces as your desktop wallpaper) · math-sonify (dynamical systems turned into real-time audio) · chaos-rpg (a roguelike where the math decides everything) · tft-synapse · lolcoach

iPhone apps

Ironbook workout log · Chain habit quilt · Minder body-doubling focus timer · Clear the Strait · Glyphstorm · Pocket Beings · Climbbook · Cutoff · Parked · Race Pace · Race Fuel · Quiver · Rooms · Clockout · Odometer · Curve · Pricebook · Pawprint · Chores · Fairway Ledger · Baseline Ledger

All native SwiftUI.
