Roman I.

I build Unity apps people actually use - AR/VR experiences, mobile games, multiplayer titles, museum and kiosk installations, spatial configurators. 13 years in Unity, 6 of them focused on AR/VR/MR: ARKit, ARCore, Meta Quest. Most of what I ship goes past a single-player demo. I've built real-time multiplayer with Photon and Unity Netcode, Firebase and AWS backends for auth and user data, and physics simulations most Unity devs never touch - rope, liquid, soft body, molecule interactions, procedural mesh generation from LiDAR scans. I also take apps through the full store cycle: IAP setup, Google Play and Apple review, post-launch fixes. On the engineering side, I profile early, fix memory leaks before they turn into crashes, and keep the app running smoothly on the low-end hardware your actual users have, not just your test device. Code is modular and documented, so your team can pick it up after I'm gone. Tell me what stage you're at - MVP, mid-project, or final polish - and let's talk about what you're building.
