Experience
MoWAKi
https://www.mowaki.org/Modern Web Application Kit (MoWAKi) is a pre-configured set of frameworks and libraries that can be used to quickly kickstart the development of a modern web application.
Uses Python, React, GraphQL, PostgreSQL, and others. Quite opinionated, but it doesn't lock users in any of the choices (you end up with a "Python+React" app, not a "MoWAKi app").

PyQL (Library)
https://github.com/rshk/pyqlA Python library providing a more high-level and user-friendly way of defining GraphQL schemas.
Based on top of graphql-core, allows schema definition in a more "Pythonic" way, greatly reducing the amount of repetitive, boilerplate code needed, while trying to stay away from "black magic" that could get into the user's way.

Python-PCAPng
https://github.com/rshk/python-pcapngA pure-Python library for reading and decoding packet capture database files generated by tools like Wireshark in pcap-ng format.
The library allows parsing the pcap-ng binary format into Python data structures that can be used for easy access to the data.
