Worlds people want to step into.
I’m Kasia, a Lead Interactive Developer specialising in Unity and XR. I build games and experiences for VR, AR, mixed reality and smart glasses, from Meta Horizon Worlds titles to Meta Ray-Ban Display apps, and use AI-assisted workflows to ship them faster.

Craft that ships. Not just demos.
- 01
Prototype to launch
I lead the technical side from first playable to release on Meta’s platforms, so ideas get tested in a headset or on a phone within days, not weeks.
- 02
Built for the device
Headsets, phones and glasses each have their own limits. I build within frame budgets, with input that never strands the player and UI that reads on every display.
- 03
AI in the workflow
Claude Code, custom MCP servers and AI skills that speed up prototyping for the whole team, and turn projects into templates others can build on.

Engineer by training, builder at heart.
I’m a Lead Interactive Developer at KoffeeCup, where I guide the technical side of XR games commissioned by Meta for Horizon Worlds, from first prototype to launch, on VR and mobile. Before that I spent four years at CinematicVR building Unity VR and AR apps for brands, museums and public institutions.
I hold an engineering degree in IT and care about clean, maintainable code as much as how an experience feels. Lately I’ve been building AI-assisted workflows with Claude Code and custom MCP servers that cut prototyping time for the whole team.
Working remotely from Poland (CET). Open to B2B contracts in Europe and C2C contracts in the US, and happy to work across any time zone.
