I contributed actively to Django from 2010 to 2016 and occasionally since then. I was a core developer until we removed that role. I led efforts to upgrade the project's organization in 2014. I served on the technical board.
In addition to these features, I made smaller improvements or fixed bugs in many components, including the ORM, the template engine, HTTP handling, sessions, generic views, and more.
I maintained the Django Debug Toolbar from October 2013 to May 2014 and brought it to version 1.0.
I presented my work at Django conferences. Videos and slides are available on my talks page.
django-sesame provides frictionless authentication with "Magic Links". It generates authentication tokens such as: https://example.com/?sesame=zxST9d0XT9xgfYLvoa9e2myN. Then it authenticates users based on these tokens.
django-sequences generates continuous sequences of integers. Some use cases like accounting require continuous numbering. Django's auto-incrementing integer primary keys don't guarantee this property.
django-transaction-signals is merely a rant aganist transaction signals.
django-userlog is a fairly impractical attempt at knowing who does what on a Django site in real-time.
