Personal Projects

Repo: Me.Memory (WIP)

https://github.com/MarvinDrude/Me.Memory
SINCE 08-2025
  • Developed an internal C# library for advanced memory- and buffer-management, including span-based and pooled data structures.
  • Structured code to optimize reuse and reduce GC / heap pressure, using buffer pooling and span etc.
  • Maintained the library as a shared internal dependency across multiple projects to ensure consistent performance and reduce duplicated effort.

Repo: CodeAnalytics.Engine (very WIP)

https://github.com/MarvinDrude/CodeAnalytics.Engine
SINCE 07-2025
  • Created CodeAnalytics.Engine, a tool that turns C# solutions into actionable, rich insights by parsing .sln / .csproj structures, source files, dependencies, and metrics.
  • Developed a lightweight console collector that scans codebases and emits normalized metadata + metrics.
  • Designed and implemented a Blazor-based Web Viewer enabling interactive exploration: source browser, file/folder navigation, symbol occurrence search, definitions lookup etc.
  • Integrated features such as syntax highlighting, file/directory hierarchy visualisation, and navigable symbol definitions across the code base.
  • Structured solution into modular components (Collector, Common, Contracts, Web Viewer) to separate concerns and maintain extensibility.

Repo: CodeGen.Core (WIP)

https://github.com/MarvinDrude/CodeGen.Core
SINCE 06-2025
  • Designed and implemented a lightweight C# source generation library (CodeGen.Core), with utility structs and classes aimed for future .NET 10 support.
  • Engineered a zero / low allocation text writer (“CodeTextWriter”) enabling efficient code generation with minimal heap overhead.
  • Built an abstracted builder layer (“CodeBuilder”) atop the writer to support both stateful and immediate code building patterns, maintaining performance while offering flexible APIs.
  • Supported advanced features like namespace & using declarations, nullable context, auto-generated code comments, method and class declarations with base classes/interfaces, parameters, indentation control etc., all with performance in mind.
  • Developed unit testing (CodeGen.Core.Tests) and performance benchmarking tools (CodeGen.Core.Perfs) to ensure correctness and efficiency.
  • Maintained code clarity and extensibility by separating concerns (common structs, core logic, performance, tests) across modules.
