Nathan Kellenicki is a Principal Software Engineer with 11 years building high-availability, service-oriented systems across gaming and fintech, currently driving platform work at Improbable. He has deep hands-on expertise in Node.js, Go, C/C++, Redis, Cassandra and AWS, and a strong track record creating scalable online services for PlayStation, Media Molecule and Monzo. Nathan blends systems-level engineering with front-end fluency (React/Redux, HTML5) to deliver end-to-end APIs and infrastructure, often shipping complex distributed features under tight product timelines. An active privacy and open-source advocate and longtime cyclist, he brings pragmatic engineering leadership and a habit of questioning assumptions—what he jokingly calls “jovial grumpiness”—to collaborative, fast-moving teams.
