- Implemented Control Flow Flattening as a custom LLVM FunctionPass, replacing structured control flow (if/else, loops) with a dispatcher-driven flat state machine over LLVM IR basic blocks, increasing cyclomatic complexity by over 300%. - Wrote a Polymorphic String Encryption pass using compile-time pointer rewriting and 4 substitution cipher schemes; developed a Dead Code Insertion pass synthesizing semantically inert IR instructions (dead stores, opaque predicates). - Built a Telemetry Analysis pass instrumenting the IR to emit compile-time metrics and generate side-by-side CFG visualizations for pre/post-transformation comparison. - Implemented safety analysis to identify and exempt volatile constructs (inline asm, setjmp/longjmp) from transformation, achieving 0% functional regression across 25+ C/C++ test programs.
