Web developer since 2003, server provider, music producer and streamer from Frankfurt. I bring ideas online as web applications, bots and streaming tools — and arrange video game music you can listen to on Spotify, Apple Music & more.

05Live on Twitch

Clone Hero live — with lots of tech tinkering

I regularly stream Clone Hero on Twitch and keep building funny and interesting gadgets into my streams.

I have traveled to Japan every year since 2018 — and by now I also stream IRL live from there.

07About me

Developer, host, producer

I'm Epyx — a programmer, server provider and music and video producer, out of pure passion. I've been building for the web since 2003, creating applications, bots and tools that support communities and streamers day to day.

My music is made with a lot of love for detail and quality: arrangements and compositions from the world of video games, released on Spotify, Apple Music and other platforms.

My great passion is also Japan: I have traveled there (almost) every year since 2018 and by now I stream live from there as well. And when I am not coding or making music, you will find me on Twitch playing Clone Hero.

I hope you enjoy it as much as I enjoy making it. ❤
