Summary
🤩
Rockstar🎓
Top SchoolAndriy Berestovskyy is a software engineer with two decades of systems and low-level engineering experience and four years focused on distributed systems and performance. He has driven core execution, deterministic memory tracking and query caching at DFINITY—contributions that enabled massive instruction scheduling and meaningful cache hit improvements—and now works at Ripple on scalable blockchain infrastructure. His background spans kernel-space networking with DPDK, real-time ETL and time-series platforms, and early work building telecom billing and instrument control systems, giving him a rare blend of networking, storage, and systems performance expertise. An active open-source contributor, he has contributed fixes to the Internet Computer reference implementation and maintains a history of engineering across ARM64, WebAssembly, and sandboxed runtimes. Based in Lausanne, he pairs a strong applied-math education with pragmatic engineering, often tackling hard determinism, instrumentation and performance problems that sit between research and production.
