Roman is a developer of compiler for neural networks in Russian Samsung R&D center. That compiler generates code for NPU (Neural Processing Unit). Compiled neural networks are deployed in flagship phones as such Galaxy Note 10. Also he worked as a developer of optimizing compiler for Elbrus and SPARC microprocessors from C, C++ and Fortran input languages. He has implemented: - architecture-independent and architecture-dependent optimizations; - C++ zero-cost exception handling in middle-end of optimizing compiler; - AddressSanitizer, MemorySanitizer and LeakSanitizer in compiler as well as porting compiler-rt library for Elbrus platform.
