Now. Tech lead at Alice Games on Vacation Cafe Simulator, a 4-player co-op cafe sim on Steam. Released 20 August 2026, Very Positive Steam rating. I own the Unity architecture, rendering and performance, the multiplayer client, and the engineering standards of a team of about ten.

Before that. Seven years at Vizex, 2016 to 2024. First city-scale 3D digital twins built from map (GIS) data, then from 2019 the virtual laboratories line I started, which became the company's flagship: 20+ laboratories on PC, iOS, Android and WebGL, 2.8M+ users. Before Vizex, AR coloring books for preschoolers.

3D is the long thread. I started in 3ds Max as a teenager, worked as a 3D visualizer before I wrote production code, and still author my own assets in Houdini. Most of what I build sits where geometry, physics and rendering meet.

On my own time. Sangria, a node-based procedural mesh framework for Unity. Experimenters, a virtual electricity lab that runs in the browser. Both are on the projects page.

This blog covers Unity internals, mesh data, Houdini-to-Unity pipelines and running 3D generation models on a DGX Spark.

Contact, work record and the full CV are on the CV page. Production work is in the portfolio.
