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). I’m also a volunteer room steward at The National Museum of Computing, as I have a personal interest in historic computing and World War II espionage.

This blog focuses on programming, but that’s not the only topic – I write about anything I find interesting or worth sharing. It also serves as a way to sharpen my skills in writing, and improve my ability to explain my ideas. The site name is a handle I use everywhere – my name and my initials.

I hope you enjoy the site.
