Summary
🤩
Rockstar🎓
Top SchoolAJ Schmidt is a seasoned infrastructure and DevOps engineer with a decade of experience building and managing GPU-enabled CI/CD platforms, currently at NVIDIA where he led migration of 15+ large open-source repositories from Jenkins to GitHub Actions and ran self-hosted GPU runners. He combines hands-on automation (TypeScript, Go, Python), CI/CD optimization (sccache, conda, Docker), and CUDA-adjacent contributions across RAPIDS projects like cuDF, cuML, and RAFT to improve testing, builds, and documentation for high-performance ML libraries. As an Infrastructure Engineering Manager he balanced team leadership with operational ownership of on-prem and AWS infrastructure powering automated builds and deployments. Beyond code and pipelines, he brings attention to developer experience—authoring tools and test adapters that translate notebook logs to JUnit XML and streamline benchmarking metadata. Based in Philadelphia, he pairs technical breadth with practical delivery and unwinds off-hours at the piano, on the soccer field, or over a game of billiards.
