● Designed and implemented the C++/Java interop layer for a cloud CAD platform using SWIG, plus gRPC passthrough for service-to-service communication. ● Built C++ abstractions for logging, metrics, and connection management so the core CAD engine stayed decoupled from cloud concerns. ● Product shipped and captured part of the CAD market in China. ● Implemented a memory-tracking library for a mixed Java/C++ service using memory-management function overloads, enabling per-document memory attribution for CAD documents. ● Built a flamegraph generation library in C++ delivered via Conan.

● Maintained auth, configuration, MSI installation, and update modules in a 25+ year-old C++ desktop application. ● Migrated the build system from MSBuild to CMake and built shared libraries for Java cloud services. ● Implemented OAuth 2.0 / OIDC and SSO for multiple C++ applications. ● Reduced release time by 3 weeks (16%) by introducing canary release capability; built observability and routing infrastructure that reduced major-incident downtime costs by an estimated $5M/year.

● Supported and delivered the C++ SDK for KasperskyOS to partners. ● Built and patched system-level modules in C/C++, maintained the GNU Make build system, and ported CLI utilities (ping, traceroute, dig, ls) to system services with C++-callable RPC interfaces. ● Designed and developed the security audit service component for KasperskyOS using C++ and SQLite. ● Hosted 100+ technical interviews for C++ engineer roles.

● Delivered highload network traffic analysis service with up-to 40 Gbps throughput. ● Achieved high performance using Linux kernel bypass with DPDK and C/C++ DSA. ● The product was sold to 3 telecom operators and generated up to 20,000 ads impressions/hour per instance.

● Developed internal tools for traffic capturing and analysis up to 100 Mbps. ● These tools helped 3 SOC specialists in their day-to-day work.
