Hi, I'm Olivier
I build production backend systems, game server infrastructure, and scalable web platforms. Currently shipping Boxhunt.pl to 13k+ users.
About
Let's keep it simple
I'm a 16-year-old Java and backend developer from Poznań, Poland. I build Minecraft networks, client-side mods, and web platforms for real businesses.
My main project is Boxhunt.pl , a Minecraft network I built and run completely solo. It peaked at 1,300+ concurrent players and has a 13k-member Discord community. I wrote a fully custom Java core for it from scratch that handles all the server systems.
I also build and maintain client-side mods. TwemojiChat runs on Fabric, Forge, and NeoForge across around 19 Minecraft version combinations. On the side I do freelance web work for real businesses.
I'm looking for opportunities to build serious systems and work with people who move from idea to production without unnecessary friction.
