Questions clients ask

How do I pay?

50% upfront before I start and 50% before the final files are delivered. Jobs of $20 or less are paid in full upfront. I invoice through Frilans Finans, so you get a proper invoice.

How many changes do I get?

Two rounds of changes are included in every package. Extra rounds are $10 each. New features outside the agreed scope get their own quote.

Which Minecraft versions do you work with?

Mainly Fabric on the latest versions (26.x). Tell me your version and loader and I'll confirm before quoting. Forge and NeoForge are possible on request.

Do I get the source code?

Full packages include source. For Starter and Standard, source is +50% unless agreed in the quote. You can always use the finished work on your server or game.

Can you show my project in your portfolio?

By default I may show finished work in my portfolio. Just ask and I'll keep it private.

What if I need to cancel?

If you cancel after work has started, the upfront payment isn't refunded. If I cancel, you get a full refund.

About me

Hi, I'm Janxirus

I study Software Engineering at Blekinge Institute of Technology in Karlskrona. Outside class I build the tools and games I want to use myself, from a Minecraft launcher to a full UI overhaul with fifteen themes.

I care about two things: it has to look good, and it has to run fast.
