I am an editor at UpdateStar. I started as a support engineer, and am now specialized in writing about general software topics from a usability and performance angle among others. I telecommute from UpdateStar’s Berlin office, when I am not working remote as a digital nomad for UpdateStar. When I'm not analyzing the latest software updates, you can find me exploring new cities, immersing myself in local cultures, and discovering innovative tech trends across the globe.
