Month: 2025-06 — Repository: Mintplex-Labs/whisper.cpp. Focused on architectural refactor to improve modularity and maintainability of the ggml-cpu backend. Delivered architecture-specific modularization and updated build system; no major bugs fixed this month; overall impact: easier onboarding, faster iteration for architecture-specific optimizations, and a more maintainable codebase. Technologies/skills demonstrated: CMake build customization, multi-file architecture separation, cross-architecture (ARM/x86) support, and code refactoring with clear traceability.

October 2024 performance optimization and kernel delivery for RISC-V quantized inference. Key outcomes: - Implemented RISC-V GEMM/GEMV kernels for Q4_0_8_8 in whisper.cpp leveraging vector intrinsics to accelerate quantized data; commit 75dd198870f6c739087ec07e6ed46fd13ef3a3f1. - Implemented RISC-V GEMV/GEMM kernels for Q4_0_8_8 in llama.cpp with similar optimizations; commit fc83a9e58479e4dd70054daa7afe5184c1bbe545. - Achieved cross-repo consistency in kernel design, enabling uniform performance improvements across models. - No major bugs fixed this month; focus was on delivering high-impact performance optimizations and stabilizing integration paths. - Business impact: substantial throughput and latency improvements for quantized models on RISC-V hardware, expanding deployment options and showing practical value of RISC-V acceleration. - Technologies/skills demonstrated: RISC-V vector intrinsics, GEMM/GEMV kernel development, quantization Q4_0_8_8, C/C++ performance engineering, cross-repo collaboration.
