I am a Senior Software Engineer with over 12 years of experience building scalable systems and immersive experiences. My expertise spans backend architecture, cloud-native development, and game engineering. I am currently seeking new challenges in remote-first or fully remote organizations.

Beyond code, I am a published author and a frequent tech conference speaker, including regular appearances at the Kassel Code Meetup. I have been featured on the GoTimeFM podcast and love traveling to conferences to stay ahead of industry trends. When not coding or speaking, I’m out walking my two dogs.
