Summary
👤
Senior🎓
Top SchoolSandipan Das is a platform-focused systems engineer with eight years of experience building and upstreaming Linux kernel features and open-source tooling. Currently a Member of Technical Staff at AMD, he previously enabled hardware performance monitoring in the Linux perf subsystem and worked on memory management, eBPF JITs, and tracing at IBM’s Linux Technology Center. He is an active upstream contributor across high-profile projects—linux-next, QEMU, gem5, BCC, bpftrace and others—bringing deep Power architecture and kernel-internals expertise to simulators and monitoring stacks. His gem5 contributions added PowerPC doubleword, multi-mode, and atomic instruction support, reflecting a rare blend of ISA-level knowledge and system software craftsmanship. Comfortable moving between kernel patches and userland tooling, he often bridges hardware features to developer-facing observability tools. Based in Kolkata, he combines academic rigor from an NITK M.Tech with a sustained record of impactful open-source engineering.
