Worked on enhancing encoding interoperability in llvm/clangir by implementing Language Server Protocol 3.17 position encoding support in clangd, replacing deprecated extensions with standard-compliant negotiation of character encodings. This involved C++ development, JSON parsing, and the addition of regression tests to verify UTF-8 offset handling, ensuring robust client compatibility. Later, focused on improving numerical reliability in SYCL-based softmax operations for ggml-org/llama.cpp and ggml-org/ggml by correcting max-reduction logic across threads. Leveraged GPU programming, parallel computing, and algorithm optimization to address accuracy and stability issues, collaborating across repositories to align SYCL behavior and reduce the risk of incorrect probability calculations.
