The most amazing...
...project I've worked on is the web framework Django. It's very rewarding to contribute components and features that are now used worldwide.
Employment
Experience
- Djangohttps://www.djangoproject.com/
Django has become a world-leading Python web framework—for perfectionists with deadlines—used by large companies like Instagram and Pinterest and many thousands of smaller ones.
I joined the team as a core developer in 2006, and I've worked on a range of components—including contributing to the CSRF protection and parts of the template parser and many smaller features and fixes, often security related. - Django-Functesthttps://github.com/django-functest/django-functest/
A testing library that allows tests to be written using a high-level API which is translated down to either an HTML/HTTP/WSGI based execution method or to Selenium. This is especially useful for traditional web sites that use a "progressive enhancement" approach to JavaScript.
I wrote the library, extracting it from several projects that needed the functionality, and am currently maintaining it. - Christian Camps in Waleshttps://www.cciw.co.uk/
I created and maintain the website for this charity. As a volunteer staff member, I analyzed and converted existing paper procedures into online versions (staff application, reference collection, police checking and camper booking and secure payment).
Due to handling sensitive information, it has to be done to the highest standards, with carefully implemented permissions that cope with continual roll-over of staff.
This project benefits greatly from its use of Django and has extensive functional and unit testing. I have also used charting and visualizations to highlight problems and progress with regard to compliance with the charity's own regulations.
All source code is released under an open source license. - Learn Scripturehttps://learnscripture.net/
This is a Bible memorization website that I created and maintain. It sports a streamlined and accessible interface, simple enough to be used by children while also working well for adults, plus motivational and social features to keep users' interest.
From the beginning, it was designed to work well on mobile devices in terms of being responsive to screen size, touch screens, and bandwidth constraints.
To support some of the testing methods that users choose, it uses Markov chains for textual analysis to generate candidate word choices.
Implemented using Django, Celery, PostgreSQL, and jQuery. - Django-PayPalhttps://github.com/spookylukey/django-paypal/
A library to bridge between Django and PayPal; it got 400 stars on GitHub and I'm currently the sole maintainer.
- Ensuring Clean Code: A Look at Python, Parameterized (Publication)We’ll explore the application of parameterization and how it relates to mainstream design patterns such as dependency injection, strategy, template method, and others. In Python, many of these are made unnecessary by the fact that parameters can be callable objects or classes.
