Projects

Project What it is
Fission My primary project — a Rust-native reverse-engineering workspace and decompiler using Sleigh/P-Code with its own NIR/HIR pipeline, aimed ultimately at rebuilding working programs from binaries.
Reversecore MCP An MCP server that exposes reverse-engineering, malware-analysis, vulnerability-research, and forensic tooling to AI agents through structured interfaces.
EverPlanet Reverse Engineering Static and dynamic reverse engineering of the discontinued EverPlanet client, including its network protocol, resource formats, authentication flow, and local server-emulation experiments.
Reforge MCP Experimental agent-oriented pipeline for analyzing existing C/C++/Java/Python/Go projects, porting them to Rust, and validating behavior against the original.
Rust Motion Browser-free programmatic video rendering in Rust with a native scene graph, CPU/GPU rasterization, FFmpeg pipelines, and optional Dioxus authoring.
Eon A Rust/Dioxus workspace that models several traditional astrology and divination systems as explicit, reproducible rule and calculation engines.
