Experience

  • Graph Assembly
    https://www.graphengine.io/

    A lower-level programming language designed for high-performance usage for Microsoft Research's distributed computational graph engine. I designed the language and implemented the specification interpreter in C++ and the compiler in C++ and LLVM.

  • Cogent
    https://github.com/NICTA/cogent

    Cogent is a purely functional, system-level programming language. I initiated and implemented the LLVM back end for its compiler, using Haskell. In addition, I supported the interoperation between Cogent and C via LLVM.

  • Bytecode
    https://pypi.org/project/bytecode/

    Bytecode is the Python library for generating Python bytecode. I added a proper stack depth computation functionality to it so that code generation will not generate codes that will cause a runtime crash due to stack underflow.

  • LICPP
    https://github.com/Z-Shang/LICPP

    LICPP is a header-only C++ library that heavily utilized modern C++ templates to provide a Lisp-flavored C++ experience and included many Lisp concepts, such as mapping, reducing, and multiple variable binding.

  • Immutable X
    https://www.immutable.com/

    Immutable X is an L2 exchange for trading NFTs on the Ethereum blockchain. My contributions include the core engine and the public API components in Go, the database in PostgreSQL, the committee node in Python, and the request handling library in TypeScript.
