Software Projects / Open source
I publish and maintain open-source software tools on GitHub. These are the most important:
A modern Python framework for polite, fault-tolerant web crawling and large-scale downloads, with a database-backed queue, deduplication, file versioning and progress reporting.
A fast asynchronous link checker for HTML, Markdown and TeX files that caches results, normalises URLs and works both from the command line and in CI pipelines.
A Python package for validating, normalising and standardising user input, with utilities for parameters, URLs, email addresses, hashes and basic security checks.
A lightweight Python library for package authors that checks Python and OS compatibility, warns about untested versions and reminds users to update before runtime issues hit.
