Anton Ugarov
C++ Software Engineer

Developing a high-load C++20 backend for real-time telemetry and event aggregation, efficiently processing and manipulating large-scale data streams at 200Mbps per core.

• Leveraged C++ coroutines with the Seastar framework for efficient concurrency.
• Improved overall data throughput by 50% and reduced service memory consumption by 30% by optimizing a single component in the system.
• Utilized the Ragel state machine compiler reducing the parsing time of standard event formats (SyslogBSD, CEF) by 70%.
• Led availability enhancements, eliminating downtime during service upgrades
• Built a sandbox service for debugging data aggregation with step-by-step insights.
• Reverse-engineered and implemented a proprietary 3rd-party binary protocol.
• Managed a four-person engineering team, coordinating development efforts.

Developed a lightweight cross-platform C++20 library enabling immersive AR try-on experiences on mobile devices.

• Designed a universal C API for seamless interaction with native frontends.
• Built a generic 3D viewer with smooth animations and high performance at 60FPS, establishing it as a core offering for the company.
• Optimized 3D rendering pipelines for enhanced real-time performance.
• Integrated a new render engine unlocking realistic reflections and materials.

Developed a high-load C++17 backend for Yandex.Messenger, serving 20kRPS, with a focus on efficient and secure asynchronous code to ensure system resilience.

• Contributed to core service components: Json/Protobuf APIs, message processing pipeline, and data storage (PostgreSQL/YDB).
• Boosted system scalability by implementing sharding and load balancing, resolving bottlenecks in the support-automation service.
• Optimized in-memory cache storage, reducing RAM consumption by 10%.
• Integrated probabilistic data structures to count unique message views in large channels, reducing the space complexity significantly.
• Gained Python experience while developing the auxiliary services.

Developed a cross-platform C++14 / Boost library for the business logic of an Android/iOS courier app.

• Redesigned architecture, cutting time-to-market for new features by 30%.
• Developed a middle-end layer to integrate the backend with platform-native frontends using JsonRPC and Djinni-generated bridges.
• Mentored a junior developer to independently deliver key features in 6 months.
• Built a generic component for automatic data caching to a local SQLite DB.
