Wolf Vollprecht
Founder at prefix.dev
Berlin, Germany
Summary
🤩
Rockstar🎓
Top SchoolWolf Vollprecht is a founder and seasoned software engineer with 14 years of experience building high-performance scientific and DevOps tooling from Berlin. He has led technical teams at QuantStack and now runs prefix.dev, blending deep C++ systems work (xtensor, xsimd) with packaging and distribution expertise across the conda ecosystem. His open-source contributions show a rare combination of numerical library optimization, SIMD/ARM support, and practical build/CI automation—everything from improving AVX512/NEON performance to making micromamba-based installers robust. He also bridges robotics and data-science workflows, enabling live ROS visualizations in Jupyter and advancing Jupyter container tooling like repo2docker. Comfortable across low-level performance tuning and higher-level packaging/automation, he’s equally at home writing SIMD intrinsics or streamlining cross-platform installers. An ETH Zürich-trained roboticist, he brings academic rigor to production-grade developer infrastructure.
