I am an academic and contract developer based in Derbyshire in the UK.

My open source work includes significant contributions to webassembly python on the pyodide project, including quite a few ports to WASM, e.g. urllib3, fastparquet, and an in progress port of Apache Arrow. I have also contributed bugfixes to projects including the python itself (cpython).

I'm also a developer on the Blendercam project, which brings support for CAM machining and CNC to the blender 3d software. I did a lot of work modernising the project to use efficient numerical processing libraries, adding continuous integration, testing and automated updates.

In my other work I do a lot of work with virtual reality headsets, machine learning and sensor processing.

I can work in most languages, I've got open source contributions on things written in C++/C, Python, JavaScript, Rust etc.

I take contract work with preferential rates on open source projects, contact me on joe@joemarshall.org.uk if you're interested in that, or I'm happy to accept sponsorship on here for one off things or if you just like something I've worked on.
