Six years at Uniregistry on top of Pyramid and SQLAlchemy, plus more recent Django REST Framework work. I started writing Python in 2008 during undergrad and it’s been my most-used language since.

Tools I reach for

• IPython for REPL work, with a customised production shell that auto-imports the models I tend to poke at.
• Sentry for error monitoring.
• Jupyter for data work and as runbooks for operational sequences.
• devpi-server as a local PyPI mirror — useful on CI and on flaky networks.
• pytest. Worked on a suite of around 8000 tests at Uniregistry (fixtures, xdist parallelisation, plugin authoring).
• uv for Python tool installs, virtualenvs, and version management.
