Projects

Static recompilers, OS tooling, byte-matching decompilation, and native game ports — all open source.

I like projects where a clean user-facing experience depends on hard systems work: runtimes, graphics paths, filesystems, toolchains, and reverse engineering.

Static recompilation of a PlayStation 2 game to a native executable

A from-scratch static recompiler and runtime that lifts PlayStation 2 MIPS machine code and VU microcode — to LLVM IR and compiles it to a native cross-platform executable.No high level emulation, no just-in-time compilation, and no interpreter differentiates my approach from emulators that exist today.

RustC11ARM/Thumb

Zero-interpreter static recompiler and runtime for Game Boy Advance

A Rust toolkit that translates GBA cartridges ahead of time into native executables. A custom ARMv4T/Thumb decoder lifts every reachable block to IR and emits C11, backed by a complete hardware model — PPU, APU, DMA, timers, saves — with no JIT anywhere.

Byte-matching GBA decompilation driven by a multi-agent LLM pipeline

A matching decompilation of a Game Boy Advance title from my childhood that rebuilds a byte-identical ROM from clean-room C source — with most of the work performed by an orchestrated fleet of LLM agents, each verifying its output against the original binary.
