I'm a compiler engineer. I worked mainly on GCC and Go, where I was responsible for support of newest x86 ISA extensions such as AVX512. I also took part in OpenMP 4.0 and Cilk+ implementation in GCC. I have a strong performance analysis and algorithmic skills, as well as deep knowledge of compiler backend.

Software Development Engineer @ Worked on optimization in Go programming language toolchain. Accomplishments: • Identified a set of relevant benchmarks for Go performance measurement • Optimized functions in standard library, archiving ~10-100% speedup • Investigated deficiencies in Go code generator for AMD64 From June 2015 to Present (7 months) Software engineer @ Worked on support of newest instruction sets in x86 backend of Gcc compiler and participated in validation of Gcc's standard conformance. Key accomplishments include: • Working together with members of OpenMP and Cilk+ standard boards to provide an implementation of their respective standards in Gcc. • Contributing full support of newest Intel architecture into Gcc, including complete implementation of 5000+ intrinsic function introduced by AVX512, support for automatic vectorization and related performance tuning resulting in 2% performance increase on wide range of benchmarks. • Work on better register allocation in GCC with respect to extra registers added by newest x86 architecture instruction. • Collaborating with LLVM and ICC teams in Santa-Clara and Novosibirsk to provide an extensive test suite for testing conformance of complier to Cilk+ standard. • Archiving two Intel MCC awards and Intel DPD award. • Establishing excellent working relationships with members of Gnu community, which allowed to publish AVX512-related GCC changes year earlier, without waiting for next release. From October 2012 to Present (3 years 3 months) Software Engineer (intern) @ Worked on support of AVX512 Intel architecture extension in Binutils open-source project. Typical workflow included programming in C programming language, working with Git distributed version control system, writing automatization scripts in Python programming language and using Redmine software for issue-tracking. Responsibilities: • Implementing all new instructions and their variants, present in newest AVX512 extension to x86 instruction set, in GNU Binutils project, including their support in assembler and disassembler. • Generating extensive test suite which covered all of newly added 5000+ instuctions variants with more than 20 tests per instruction. • Collaborating with GNU Software Foundation members, to assure quickest addition of new functionality to source code of relevant software packages. • Bug-fixing of GCC complier on x86 architecture based hardware. • Performance tuning, especially for mobile Intel Atom platform codenamed Saltwell. • Researching industry-acknowleged SPEC and EEMBC benchmarks in search of possible complier optimizations. From January 2011 to October 2012 (1 year 10 months)
