Summary
👤
Senior🎓
Top SchoolArjun Ramaswami is an HPC performance engineer based in Berlin with 14 years of experience bridging academic research and production software. He specializes in FPGA-accelerated high-performance computing, having developed an OpenCL FFT library (FFTFPGA) and integrated it into real-world HPC codes such as CP2K, plus optimized multi-dimensional FFTs on Intel Arria and Stratix devices. Comfortable across a deep software stack—C/C++, Fortran, OpenCL, MPI/OpenMP, Python and CI tooling—he combines low-level performance tuning with practical deployment experience on supercomputers and cluster schedulers. Previously he modernized full-stack web applications and ported autonomous vehicle workloads to ARM-based MPSoCs, showing a rare mix of hardware-aware systems work and application-level delivery. Proactive and team-oriented, he also has hands-on teaching and project management experience, supervising student projects that extend FPGA tooling into Julia for HPC.
