Worked on enhancing reliability and maintainability in compiler and Java development projects, focusing on targeted bug fixes rather than feature additions. In the substrait-io/substrait-java repository, addressed version resolution robustness by implementing a fallback mechanism in Java to default the specification version to '0.0.0' when missing, thereby reducing downstream runtime errors. In llvm/circt, improved the ESI to Physical dialect conversion by updating C++ code to replace deprecated operation sequences with a single replaceOp, aligning with upcoming LLVM IR API changes. These contributions emphasized defensive programming, dialect conversion, and proactive adaptation to evolving APIs, supporting smoother upgrades for downstream users.
