In the age of generative AI, codebases accumulate similar snippets faster—raising maintenance costs and propagating bugs.

This project delivers an IntelliJ-style on-the-fly duplicate code detector for C# (see IntelliJ Inspection).

Using ReSharper's PSI (Program Structure Interface, the code model), you'll build the resource-efficient inspection to find exact and parameterized duplicates, and a corresponding quick-fix to consolidate the code.

• Programming skills in C#, Java, or Kotlin: write readable code, comprehend IntelliJ's implementation

• Fundamentals of PL/compilers: tokenization, AST, alpha-renaming

• Problem-solving: can turn a rough spec into a prototype

• Communication: written/spoken English and willingness to collaborate asynchronously

Nice-to-haves:

• Hands-on IDE tooling (ReSharper/Rider/IntelliJ)

• Basic use of profilers to validate performance
