Summary
🤩
RockstarGergely Nagy is a Principal Software Engineer with over 22 years of hands-on experience building and improving software across embedded, back-end and tooling domains, now focused on ML accelerator software at ARM. He combines deep systems-level craftsmanship (firmware for keyboard projects, syslog-ng, embedded MCU work) with strong tooling, CI and devops practice to speed partner productivity and ship reliable platforms. Known for rigorous testing, refactoring and API evolution, he blends TDD/BDD and continuous improvement with pragmatic engineering across Java, C/C++, Ruby and scripting. An active open-source contributor, he’s added core-language features to Hy and meaningful firmware enhancements to Keyboardio and QMK, showing both low-level finesse and language/compiler understanding. Curious about functional languages and NLP/ML, he actively seeks exposure to Clojure, ClojureScript, Scala and Rails to broaden his toolbox.
