My open-source work focuses on building tools for C++ developers that bringing ideas from functional programming (Clojure, Elm, Haskell) in idiomatic and performant ways. Some of my projects have been talked about at top-tier C++ conferences and are used in production by commercial projects:

  • Immer, a high performance library of immutable and persistent data-structures
  • Lager, a data-model library implementing Unidirectional Data-Flow design to interactive applications
  • Zug, a library for reactive sequential transformations

I am a consultant focusing on modern C++, value-oriented design, interactive software, open-source strategy and music technology. Before I worked for Ableton, contributed to GNU, and cofounded a Hacklab in Granada. Most of my clients work in the music and interactive software industry. Besides the stimulating creative aspect, I really like the blend of critical performance and real-time constraints with complex high-level interactions and user facing features.

I have a strong vision for a future C++ where value-semantics are the default mode of thinking of a C++ programmer, and there are lots libraries and tools I would like to build to support it. Help me! ❤️

Let's get up to 1000$/month again in order to implement hash maps and set transients on Immer!
