Hi, I'm Sebastian. Software developer in Vienna, by day at Sensor Network Services. In the evenings I build
Clunema, club software with a cash register. Almost everything before that exists because a tool was missing:
Playbook, so my CS2 team can practise grenades, and
VNC Beach, because I wanted a VNC client that costs nothing.
Selected projects
all projects
Rust · macOS & Windows
VNC Beach
VNC server and viewer, free and open source. Speaks standard VNC, transfers only changed screen tiles and shares several monitors as one desktop.

Club software
Clunema
Events, fees, polls and messages for members, departments and teams. Plus a cash register that also books without internet.

Counter-Strike 2
Playbook
Lineup library, in-game grenade training, teams and strats, demo analysis and server management. With its own CounterStrikeSharp plugin, in-game HUD and Windows app.
About me
I mostly write software when I or the people around me are missing a tool. That is how a training server for the CS2 team came about, a cash register for the club and a VNC client in Rust.
I like working with TypeScript, React and Convex best. When it has to be fast and close to the system, Rust. On GitHub since 2020 as realS3BI.
