Estevan Vedovelli contributed to the ROCm/hipTensor and ROCm/composable_kernel repositories by developing features and fixes that improved build reliability, test infrastructure, and hardware support for high-performance computing workloads. He modernized C API headers and header guards, introduced dynamic architecture queries in CMake, and enhanced logging and resource management for more deterministic testing. Estevan also delivered FP16 and BF16 support for tensor contractions, enabling WMMA hardware acceleration on newer GPUs, and addressed debugging clarity through improved assertion handling. His work demonstrated depth in C++ development, build system configuration, and GPU programming, resulting in more maintainable, robust, and hardware-aware codebases.
January 2026 focused on delivering a high-impact feature for ML/HPC workloads alongside a critical bug fix to improve debugging and build reliability. All work centers on ROCm/composable_kernel, with clear business value through hardware-accelerated tensor contractions and more robust development workflows.

Month 2025-10: ROCm/hipTensor focused on modernization, builds reliability, and hardware-aware deployment. Key features delivered include: 1) C API headers and header guard modernization, introducing C API headers for C compatibility, upgrading to C++20, deprecating older C++ headers in favor of C-style headers, and standardizing header guards to improve compatibility and readability, addressing build issues such as hiptensorGetVersion redefinition. 2) Dynamic architecture query support in the build system, adding a new CMake function and script to query supported hipTensor architectures, enabling dynamic build configuration based on hardware capabilities. Major bugs fixed include the build error related to hiptensorGetVersion redefinition during the C API headers modernization. Overall impact: improved build reliability across compilers and platforms, easier downstream integration, and more efficient hardware-targeted builds, setting the stage for future performance optimizations and maintainability improvements. Technologies/skills demonstrated: C API design, C++20 modernization, header guard standardization (#pragma once), CMake scripting and build-system hardening, architecture-aware build configuration, and proactive build reliability fixes.
