Tamás Zolnai is a Senior C++ software engineer with 13 years of experience building robust backend and hardware-adjacent systems across medical imaging, industrial automation, robotics, and collaborative office software. He has shipped production-grade components that span OPC UA integrations for manufacturing, shared-memory and ZeroMQ/HTTP/ WebSocket microservice communication for medical visualization, and safety-critical navigation and firmware interfaces for mobile robots. A long-time contributor to LibreOffice/Collabora ecosystems and to clang-tidy checks in the LLVM mirror, he blends deep systems-level C++ expertise with practical test automation and UI work (Cypress, Squish). Tamás’s dual academic background in computer science and psychology gives him an unusual edge in designing human-centered tools and testing strategies. Colocated in Budapest, he favors improving tooling and code quality—often by tightening static analysis, tests, and documentation—to make complex systems more maintainable. Colleagues know him for reliably closing tricky integration gaps between hardware, security, and scalable software services.
