Projects

  • claude-shell

    A Go wrapper around the Claude CLI that provides isolated, containerized sessions for concurrent use.

  • CRSCE

    CRSCE is a research proof-of-concept compression format and toolchain that encodes a 511×511 bit Cross‐Sum Matrix (CSM) per block using four families of cyclic cross‐sum constraints and per‐row SHA‐256 Lateral Hashes (LH). The project ships two C++23 binaries, compress and decompress, built with CMake/Ninja and verified by CTest. The format prioritizes integrity and deterministic verification; it does not provide confidentiality.

  • Asymmetric Effort GreyNet

    GreyNet provides decentralized, peer-to-peer zero trust network access without reliance on centralized control planes. Nodes authenticate and authorize each other directly using cryptographic identity, establishing secure channels only after mutual verification.
