Summary
🤩
Rockstar🎓
Top SchoolVraj Pandya is a seasoned software engineer with 11 years of experience specializing in concurrent programming, back-end systems, and database engineering, currently building software at Apple in Sunnyvale. He has a strong C/C++ and GPU compute background from graduate research that yielded a 20% performance gain over cuBLAS/MKL through auto-tuning BLAS kernels and heterogeneous MPI+CUDA clusters. At OmniSci and as a contributor to HeavyDB, he implemented backend features such as shared dictionary support and performance optimizations for string dictionaries, demonstrating deep familiarity with high-performance analytics databases. Comfortable across systems from embedded UDP services to large-scale HPC and production backend services, he pairs low-level optimization skills with pragmatic engineering processes. His blend of academic research and production experience makes him adept at squeezing performance from hardware while delivering maintainable, scalable systems.
