Led a cross-functional team to deliver Quest-first standalone VR training simulations. Architected SOP-driven VR training simulations for Meta Quest, reducing client onboarding costs by 30% via a data-driven, configurable scenario system. Bridged Unity clients with enterprise backends, implementing secure RESTful integrations for authentication and cloud-hosted data on AWS/Azure. Optimized standalone VR performance, achieving a ~50% increase in frame stability through deep profiling of draw calls, memory leaks, and GPU bottlenecks. Developed a cross-platform multiplayer framework using Photon for synchronized, multi-user enterprise collaboration sessions.
Technologies Used: Unity, C#, XR Interaction Toolkit, Meta Quest, HTC Vive, REST APIs, Git
Senior Game Developer / Founding Team Lead
Alantrix Geim StudiosSep, 2025 - Dec, 2025 3 months
Engineered a high-velocity production pipeline that delivered ~70 hyper-casual games in 8 weeks using modular C# templates and automated build workflows. Established engineering standards, including strict code reviews, SOLID-based architecture, and CI/CD delivery workflows. Mentored a team of 15 junior developers, focusing on production readiness, debugging patterns, and clean architecture. Accelerated iteration by shipping weekly playable prototypes, enabling stakeholders to validate mechanics (e.g., Knife Orbit dash-and-slice) in real time.
