Summary
🤩
Rockstar🎓
Top SchoolAlberto Invernizzi is an HPC scientific software engineer with 11 years of experience building high-performance C++ systems, embedded vision platforms, and robust tooling for scientific computing. Currently at CSCS in Lombardy, he combines low-level optimization (SSE, multithreading, CUDA) with system integration and DevOps skills, having introduced NVIDIA Tegra SoC support and production-grade SDKs in prior roles. He contributes to prominent open-source projects like cppzmq and Spack, improving CI, testing, and package management for widely used C++ and HPC ecosystems. Comfortable across the stack, he has shipped camera drivers, cross-compilation toolchains, and automated test suites, and he often bridges software and hardware by debugging firmware and tuning embedded platforms. His academic background (MSc with honors) and history of tooling in Python for data analysis reflect a pragmatic research-to-production mindset. Notably, he focuses on reproducible builds and CI reliability—small improvements that consistently speed up teams and scientific pipelines.
