What I'm looking for

I’m looking for remote or hybrid work in Canada, where I’m eligible to work without sponsorship or an LMIA.

At Nvizzio Creations Inc., I built ECS-native multiplayer systems with Netcode for Entities and optimized RPC traffic, physics sync, and gameplay state to support ~200 concurrent networked bots with animation and physics in the target scenario.

I also wrote the tutorial system for Tower Dominion and shipped its iOS and Android port with in-app purchases on both platforms. To address performance issues before launch, I moved cascading ability effects onto Unity’s multithreaded Job System.

Now, I’m building Satan's Ball alone in Unity and using an AI-agent workflow I designed. I also created and maintain Vahta, an open-source tool that lets AI coding agents use API keys without seeing them.
