Senior🎓
Top SchoolSounak Gupta is a Senior Staff Engineer in the Memory Systems Lab at Samsung Semiconductors with 13 years of deep expertise in distributed systems, memory and storage engineering, and high-performance C++ software. He has driven impactful low-latency and capacity-tiering innovations across Oracle, Intel, eBay and open-source projects—reducing hot-path latencies to sub-20ns, adding CXL memory tiers to CacheLib, and co-designing NVM-backed elastic block storage. His work bridges research and production: a PhD-trained systems researcher who built large-scale parallel simulators (WARPED2) and measurable data-center profilers used to improve real kernel and I/O behavior. An active contributor to multiple production GitHub projects and industry collaborations (including a hyperscaler feature-engineering benchmark with Meta and MIT), he consistently turns kernel-to-application optimizations into measurable throughputs and latency wins. Based in the San Francisco Bay Area, he combines low-level performance tuning with cloud-scale architecture design, and often surfaces uncommon wins by focusing on off-CPU batching and inter-tier data movement.
