πŸ‘‹ Hi, I’m Justin

LinkedIn Email

Senior Software Engineer at OpenTeams
Currently contributing to the PyTorch ecosystem, with a focus on high-performance GPU kernels, compiler infrastructure, and scientific computing integration.

I bridge the worlds of computational quantum chemistry and high-performance software engineering, developing tools that make large-scale scientific computation faster, more scalable, and more maintainable.


πŸ§ͺ Current Projects

Project Description Tech
PyTorch Core deep learning framework β€” GPU kernels, Inductor compiler, and performance optimization C++, Python, CUDA
Einsums C++20 tensor library for single-node and GPU computations C++20, CUDA / HIP
Psi4 Open source quantum chemistry C++20, Python

πŸ“Œ Pinned Project Showcase


πŸš€ Technical Interests

  • GPU kernel development and tensor compiler optimization (PyTorch Inductor)
  • Tensor rank reduction (DLPNO, THC)
  • Task-based parallelism & custom AGAS designs
  • Performance benchmarking & profiling tools
  • Scientific Python/C++ interoperability

"Efficient science needs efficient code."
