C++ Development (C++11/14/17/20)
Extensive expertise in modern C++ standards including C++11, C++14, C++17, and C++20, applied in production environments for low latency trading infrastructure, gateway components, and high-performance systems.
Multithreading, Concurrency & Deterministic Synchronization
Deep knowledge of multithreading and concurrency patterns, including deterministic synchronization and performance-sensitive code, used to build robust cross-product communication components and co-simulation frameworks.
Networking & Protocol Integration
Hands-on experience with networking protocols including Ethernet, CAN, LIN, FlexRay, as well as financial exchange protocols such as Eurex T7 and Euronext Optiq, supporting both automotive and trading domain applications.
Event-Driven Systems & Asynchronous Processing
Practical application of event-driven architectures using Grand Central Dispatch and libdispatch to support asynchronous processing and reliable gateway behavior in trading platforms.
AUTOSAR & Vehicle Network Protocols
Implementation of features aligned with AUTOSAR standards and vehicle network protocol requirements, including protocol-level debugging with Ethernet, CAN, LIN, and FlexRay.
Debugging & Profiling Tools
Proficient with a wide range of debugging and profiling tools including GDB, WinDbg, ProcMon, Intel VTune Profiler, as well as build tools such as Git, CMake, make, and Visual Studio.
Legacy Code Modernization
Refactoring of legacy C modules to modern C++17 templates, reducing code size, eliminating bug classes, and improving ASan/UBSan results in production environments.
Unit & Regression Testing
Addition and maintenance of unit and regression tests using tools such as gRPC and Protobuf, stabilizing failing cases and improving test coverage over time.
Additional Languages & Technologies
Working knowledge of Python, C#, Rust, STL, Boost, Windows API, and security-aware debugging, complementing core C++ development skills.

Project history
Working on gateway components for the Tbricks trading platform, focusing on exchange connectivity, protocol handling, and venue integration. Developing and maintaining C++ components related to Eurex T7 and Euronext Optiq protocols in low latency trading infrastructure. Using Grand Central Dispatch/libdispatch and event-driven technologies to support asynchronous processing and robust gateway behavior. Improved venue connection handling by redesigning part of the connection lifecycle.
Owned a cross-product communications component used across multiple features, managing concurrent connections and deterministic data synchronization. Drove design discussions across product components, documented decisions, and aligned interfaces to unblock dependent teams. Proposed and delivered release features based on customer impact and internal roadmap.
Implemented features aligned with AUTOSAR standards and vehicle network protocol requirements. Worked with Ethernet, CAN, LIN, and FlexRay protocols using tools, traces, and protocol-level debugging. Built multithreaded co-simulation between internal applications and third-party open-source libraries. Added and maintained unit/regression tests, stabilizing failing cases and improving coverage.
