Top SchoolPau Pedrol is a seasoned software developer with 16 years of experience specializing in operating systems, networking, and embedded Linux, currently based in Barcelona. He has a strong track record in low-level C work and backend protocol implementations, contributing to high-profile open-source projects like Wireshark and Open5GS where he enhanced dissectors and GTP handling. His background spans R&D and operations roles—improving Multipath TCP integration at Tessares, hardening L2TP and kernel networking code, and tuning SDR/4G testing and deployment pipelines. Comfortable across development, DevOps, and platform engineering, he combines curiosity-driven problem solving with practical production fixes and upstream contributions to the Linux ecosystem. An understated strength is his blend of protocol-level debugging skill and systems-level operational sense, enabling him to both find subtle defects and harden complex telecom stacks.
