I'm Vladimir Ulianitsky, Backend Engineer at Profitero specializing in Ruby & Python, passionate Rubyist and open-source developer. I love to explore other languages and have a keen interest in Ruby cross-language interoperability, I used C, C++, Rust to create Ruby gems and am also familiar with Golang

• 🔭 My open source projects are:

  • ffi-llvm-jit - a Ruby gem that leverages LLVM to boost FFI calls performance.
  • oxidizer - a WIP library that wraps Magnus and PyO3 and allows to create both Ruby gems and Python libraries written in Rust without code duplication.
  • ffie - a collection of "Hello World"-level examples of how to call code written in other programmings languages - Rust, Crystal, Go, C, C++, C#, Julia, Zig, D, Swift, Haskell, Nim, Java - from Ruby and Python.
  • xml2json-rb - a Ruby wrapper around the xml2json-rs Rust library using Magnus.
  • json_scanner - a Ruby gem with a C native extension that uses the yajl library to efficiently find and parse parts of large JSON strings.
  • ruby-jsoncons - a Ruby gem that allows to use JSONPath implementation from the jsoncons C++ library using Rice.

• 🤝 I also contributed into:

  • curb - a Ruby wrapper for libcurl
  • fakefs - a fake filesystem to use in tests

• 🤔 I’m looking for help with:

  • robusta, a fork of the Rust library for accessing JNI from Rust. I wanted to use it to add JRuby support to Magnus, but it requires numerous fixes, especially updating the jni-sys dependency version.
