Hi,

I'm a software developer from Switzerland, building open-source tools for the .NET and Python ecosystems.

What I build

I'm the creator and maintainer of:

• https://github.com/lduchosal/ipnetwork — A C# library and CLI tool for IPv4/IPv6 network calculations. It handles the complex math behind subnetting, supernetting, CIDR
  notation, and IP range operations so developers don't have to. Available as a https://www.nuget.org/packages/IPNetwork2 and a
  https://community.chocolatey.org/packages/ipnetwork, used by thousands of developers worldwide.
• https://github.com/lduchosal/check_msdefender — A Nagios plugin for monitoring Microsoft Defender for Endpoint API endpoints. It monitors onboarding status,
  vulnerabilities, CVE-affected products, alerts, and machine details with full Nagios-compatible output. Available on https://pypi.org/project/check-msdefender/.

Why sponsor?

These projects have been actively maintained for years. Your sponsorship helps me:

• Keep the libraries up to date with the latest .NET and Python versions
• Review and merge community contributions
• Add new features and improve documentation
• Ensure 90%+ test coverage and code quality

Every contribution, big or small, helps me dedicate more time to open source instead of billable work. Thank you for considering it!
