PROFILE
Saranya Natarajan
Worked on the SAP/SapMachine repository, focusing on stability and optimization of the C2 compiler over three months. Applied C++ and Java expertise to refactor array growth logic, centralize memory management, and enhance error reporting for unhandled bytecode exceptions, improving debugging clarity. Addressed a SIGFPE crash in unsigned modulo operations by introducing runtime checks and regression tests, and improved code readability by renaming memory accessor APIs for clearer type semantics. Resolved a macro node elimination crash by refining loop node processing and adding targeted regression coverage. Demonstrated strengths in compiler optimization, code refactoring, and test-driven development for JVM internals.
