Become a sponsor to Marcel Roozekrans
Hi, I'm Marcel — a .NET engineer building open-source libraries and developer tooling I wish existed.
What your sponsorship funds
Time. Specifically, the time I spend triaging issues, cutting releases, writing docs, and shipping new tools instead of letting them stagnate after the initial commit. Sponsorship lets me treat OSS as a recurring commitment rather than a side hobby.
What I maintain
The ZeroAlloc ecosystem — a coherent set of high-performance .NET building blocks designed to compose:
ZeroAlloc.Mediator— source-generated mediator (no reflection at runtime)ZeroAlloc.Analyzers— Roslyn analyzers that catch hidden allocations at compile timeZeroAlloc.Cache,Scheduling,Outbox,Resilience,EventSourcing,ValueObjects,Telemetry,StateMachine,Inject,Validation,Pipeline,Results,Serialisation,Collections,Rest— focused, allocation-conscious primitives
Developer tooling:
roslyn-codelens-mcp— semantic .NET code intelligence over MCP, so AI assistants can actually understand C# solutionsmemorylens-mcp— guided .NET memory analysis via MCPLongtermMemory-MCP— persistent memory backend for AI agentsMailPeek— local mail inspection tool
Why sponsor
If any of these have saved you time, prevented a production incident, or just made your day a little better — sponsorship is the most direct way to keep them maintained and to fund what comes next.
If you can't sponsor, that's fine too. Star, file issues, send PRs. All of it helps.
