Greater Stockholm Metropolitan Area Sweden
Summary
🤩
RockstarDaniel Bevenius is a seasoned software engineer with 17 years of experience, currently contributing to Hugging Face after a long tenure at Red Hat where he was a Principal Engineer and Node.js TSC member. He specializes in backend systems, runtime internals and build/tooling improvements, with deep contributions to Node.js core, libuv, OpenSSL and QUIC implementations. Equally comfortable in C/C++, Rust and Java, he has actively improved popular open-source ML and inference projects like whisper.cpp, llama.cpp and ggml, helping them build and compile reliably across CUDA/Metal targets. His work often targets subtle but high-impact areas—reducing duplication, suppressing compiler warnings, and hardening build processes—that improve maintainability across large codebases. Based in Stockholm, he combines systems-level craftsmanship with a pragmatic focus on developer experience and cross-platform stability.
