Jacob Alzén is an M.Sc. candidate in Computer Science and Engineering specializing in Secure Systems, currently writing his master’s thesis at Sectra on peer-to-peer VPNs with a distributed control plane. With nine years of hands-on experience across Linux system maintenance, embedded and full-stack development, he repeatedly contributes to open-source Go projects—improving security, stability, and cross-platform tooling such as magic-wormhole and GLFW bindings. He blends deep low-level knowledge (VHDL, operating systems, parallel C) with practical application delivery, from GUI work in Fyne to backend dependency and crypto upgrades. A former Linux package maintainer and technical reviewer, he pairs rigorous engineering with clear communication, having taught C++ and supervised data engineering teams. Outside code, he’s an avid trail runner, climber and amateur photographer, which informs a measured, systems-oriented approach to problem solving.
