Decompiler Engineering · Reverse Engineering · Agent Infrastructure · Rust Systems

I build systems for program analysis, reverse engineering, and AI-agent automation, primarily in Rust. My work spans semantics-aware decompilation and security tooling as well as headless video rendering, WebAssembly audio software, and deterministic rule engines.

Projects

Project What it is
Fission My primary project: a Rust-native reverse-engineering workspace and decompiler with Sleigh/P-Code lifting, semantics-preserving NIR, readable HIR, CFG structuring, type recovery, and execution-differential validation. The long-term goal is to reconstruct buildable, working programs from binaries.
Reversecore MCP An MCP server that connects AI agents to local tools for binary reverse engineering, malware triage, vulnerability research, crash analysis, and digital forensics. It emphasizes structured, byte-level evidence, isolated execution, and context-efficient tool routing.
Kymion An agent-first digital audio workstation built with Rust and WebAssembly. It combines a browser-based DAW, real-time AudioWorklet playback, MIDI and non-destructive audio editing, DSP effects, vocal synthesis and tuning, and a JSON-command CLI sharing the same engine.
Reforge MCP An early-stage MCP infrastructure project for migrating C/C++/Java/Python/Go software to Rust. It currently supports repository indexing, source navigation, and persistent planning state; semantic analysis, automated porting, and behavioral verification are planned.
Rust Motion A browser-free programmatic video rendering engine with deterministic scene representation, parallel CPU/GPU rasterization, FFmpeg encoding, a Remotion-oriented TypeScript SDK, Python bindings, WebAssembly playback, and an agent-friendly CLI.
Eon An experimental pure-Rust engine for deterministic calculations across Saju, Vedic and Western astrology, Zi Wei Dou Shu, Human Design, Qi Men Dun Jia, and numerology, with cross-system synthesis, structured CLI outputs, and an MCP server for AI agents.
