Alexander Couzens
Open Source Developer at fe80 - Freelance, self-employed
Berlin, Germany
Summary
🤩
RockstarAlexander Couzens is an experienced embedded software developer and long-time open source contributor based in Berlin, with 16 years delivering firmware, drivers and build-system improvements across projects like OpenWrt, coreboot and Wireshark. He specializes in mobile networks (2G–5G), wireless/802.11, x86 firmware and IoT device work, notably enabling hardware features and per-model device profiles for TP‑Link CPE devices and adding coreboot support for Lenovo models. His contributions span low-level driver development, reproducible build engineering and protocol dissectors—often fixing subtle hardware/configuration issues and build nondeterminism that break downstream deployments. As a freelance developer he combines hands-on device bring-up with DevOps-style automation for package feeds and CI, and has a habit of hunting down obscure build timestamps and calibration quirks that others miss.
