What I'm looking for

I'm looking to lead and build scalable, production-quality gameplay systems for mobile or large-scale game projects, while solving complex technical challenges, improving architecture and performance, and mentoring strong engineering teams.

I've led Unity engineering for Gear Games' mobile adaptation of XCOM, published by 2K, and the in-house title Arcane Rush, guiding architecture, performance optimization, and feature delivery across teams of approximately 10 engineers. Previously, I led Orbitau at F6 Galaxy, integrating Web3 systems, wallet connectivity, NFT ownership, and token-related gameplay features.

Across 13+ years, I've shipped mobile, AR/VR, WebGL, and live-service projects from prototype to production, including Sky Garden, Virtua Tennis Challenge, Sonic the Hedgehog 4, Crazy Taxi Tycoon, and interactive multiplayer experiences. I combine hands-on gameplay and engine-level programming in Unity and C++ with mentoring, code reviews, and practical architecture that keeps projects scalable and maintainable.
