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.
DecBench C++ Target Qualification Research workspace for C++ decompiler evaluation: corpus qualification, DWARF-backed function identity, overload collisions, and cross-decompiler validation.
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.
