Rockstar🎓
Top SchoolThomas Daubney is a Senior Software Engineer at Arm with five years of professional experience focused on open-source security libraries, notably contributing to the Mbed TLS project. He combines hands-on C/C++ backend development with a rigorous academic background—MPhys and an MPhil in particle detector physics from the University of Manchester—which informs a methodical, research-driven approach to code quality and maintainability. At Arm he has driven refactors to simplify RSA APIs and remove deprecated functionality, improving long-term maintainability and documentation for a widely used TLS implementation. Previously he applied machine vision expertise at Simsol and research skills at DESY, reflecting an ability to move between research and production engineering. He’s based in the UK and brings a pragmatic mix of security-focused engineering and scientific problem-solving to open-source cryptographic projects.
