Hi, I’m Alex.

I’m a software developer at the Wellcome Trust and an open-source Python developer. At Wellcome, I’m helping build a new platform for searching and storing our digital collections. It’s taking Wellcome’s assets – books, archives, images, and more – and presenting them through consistent, well-designed APIs.

I contribute to open source Python in my free time, including the Hypothesis testing library and the hyper-h2 HTTP/2 stack. I’m one of the organisers for the PyCon UK conference, and I’ve given a number of talks about Python (among other topics).

The site focuses on programming, with the occasional venture into accessibility, maths, bits of travel advice and Victorian engineering. It’s as a way to sharpen my skills in writing, and improve my ability to explain my ideas. If that sounds interesting, I have an infrequently updated blog.

I hope you enjoy the site.
