Freyja
Zero-config CLIs from your Python classes
A Python library that builds a complete command-line interface from one or more functions (or typed class methods) using introspection. With zero configuration and no runtime dependencies, Freyja turns type annotations and docstrings into professional CLIs — complete with type-safe argument parsing, automatic help generation, and shell completion for Bash, Zsh, Fish, and PowerShell. Available on PyPI.
Idunn
A tiny constructor-time dependency inversion toolkit
A minimal dependency injection / IoC toolkit built around just three decorators — @Port (defines a contract), @Adapter (binds an implementation), and @Invert (injects dependencies). Idunn focuses exclusively on constructor-time injection, with auto-discovery, environment-based implementation selection (dev/test/prod), keyed adapters, and transient or singleton lifecycles. Named for Iðunn, the Norse keeper of the apples of youth — a nod to keeping code fresh through clean, explicit wiring. Available on PyPI.
Modgud
Expression-oriented programming for Python
Brings expression-oriented programming to Python 3.11+ through guard clause decorators and implicit returns, eliminating defensive-coding clutter while preserving a single-return-point architecture. Declarative guards (not_none, positive, in_range, type_check, matches_pattern, not_empty, plus a custom guard registry) validate inputs before a function runs, so bodies focus on business logic instead of validation boilerplate. Zero runtime dependencies and mypy-friendly. Named for Móðguðr, the Norse bridge guardian who demands identification before passage. Available on PyPI.
CSV Batcher
Scaling vertically with CSVs and/or Pandas
A lightweight, python-based, multi-process CSV batcher suitable for use with Pandas dataframes, as a standalone tool, or other tools that deal with large CSV files (or files that require timely processing).
Python Arango Object Graph Model
This is built on top of python-arango. Capabilities include model-like access to graph objects, and a migration mechanism that generates migrations from your defined models; similar to how Django builds its migrations. This is somewhat a work-in-progress as I integrate it back into the closed-source project from which it was extracted.
Python Bunny MQ
Python-based package that implements a no-dependency, ultra-lightweight intra-process message queue. This works inside a single process. This is useful when you need a lightweight pub-sub system. For example, the author is using it in development to send message to local handlers. These handlers are ultimately deployed to AWS and are invoked as a lambda function via SQS, so the dev-time “bunny-mq” will not be used.

Ruby-Fann
RubyFann, or “ruby-fann” is a Ruby Gem (no Rails required) that binds natively to FANN (Fast Artificial Neural Network) from within a ruby/rails environment. FANN is a is a free native open source neural network library, which implements multilayer artificial neural networks, supporting both fully-connected and sparsely-connected networks. It is easy to use, versatile, well documented, and fast. RubyFann makes working with neural networks a breeze using ruby, with the added benefit that most of the heavy lifting is done natively.
PathMaster
A★ pathfinding in Unity 3D via AutoWaypoints. This was part of a Unity game that didn’t make it to market. Since Unity now has pathfinding built-in, we are open-sourcing this for posterity.
