Summary
🤩
Rockstar🎓
Top SchoolDmitry Kh is a seasoned software engineer with 12 years of experience specializing in Ethereum, C++, and game development, currently based in Spain. He contributed significant test and automation work to high-profile open-source Ethereum projects like ethereum/tests and solidity, improving RPC test reliability and debugging node startup and transaction processing issues. His background spans embedded web/admin roles and 3D visualization and game scripting, giving him a practical edge in both backend systems and real-time graphics. Dmitry’s work emphasizes robustness and debuggability in distributed systems, with hands-on expertise in RLP encoding, transaction semantics, and test framework maintenance. Comfortable across low-level C++ and higher-level scripting and automation, he brings a pragmatic, test-first approach to complex blockchain engineering problems. He holds a Master’s in Information Technology from Tver State University and has a habit of finding subtle, reproducible failure modes that reveal deeper protocol issues.
