Vladyslav – C#, Unity, Firebase

A cross-platform AR/XR skateboarding game built in Unity, shipped across iOS, Android, Apple Vision Pro, and Meta Quest as part of a 15-release commercial portfolio. The platform supports live, scalable player systems with reliable cross-device performance, and content can be updated without new builds. Player systems are architected around state machines and physics-driven movement layered on Animator, the backend runs on Firebase with Cloud Functions, and Addressables-based remote content delivery lets new gameplay content roll out post-launch. Location-based play was added via Niantic Lightship Maps integration.

• Architected the player system around state machines and physics-driven movement integrated with Animator.
• Designed and built the Firebase Database + Cloud Functions backend architecture.
• Shipped Addressables with remote content delivery, enabling post-launch content updates without new builds.
• Integrated Niantic Lightship Maps for location-based gameplay.
• Profiled and optimized Android and iOS builds for CPU, GPU, and memory usage.
• Led the cross-functional team and owned production releases across four consecutive product iterations.

A VR adaptation of the AR skateboarding experience for Meta Quest, built for stable real-time execution and believable AI-driven navigation rather than scripted paths. The gameplay mechanics were ported to Meta Quest with new progression and leveling systems and spatial VR UI, and Unity ML-Agents power AI navigation training for trick execution across dynamic obstacles — balancing ML-driven behavior against deterministic, testable gameplay.

• Ported the core AR gameplay loop to Meta Quest VR.
• Built new progression and leveling systems for the VR context.
• Integrated Unity ML-Agents to train AI-based navigation for trick execution across dynamic obstacles.
• Designed spatial VR UI and tuned performance for stable real-time execution.

An AR platform for real-world localization, using Niantic Lightship VPS to recognize physical locations and anchor interactive AR content to real-world environments. State-driven character systems and responsive AR UI flows support location-aware experiences.

• Integrated Niantic Lightship VPS for real-world localization.
• Built state-driven character systems for location-aware AR interactions.
• Designed responsive AR UI workflows.

A spatial-computing version of the AR skateboarding game for Apple Vision Pro, adapted from the AR architecture into a native spatial-computing experience without losing responsive gameplay. Navigation and player systems were redesigned for spatial input, with hand-tracking controls and spatial UI, and a replay system records trick and navigation data. The build is optimized for VisionOS hardware constraints with ongoing post-launch updates.

• Led the architecture port from AR to VisionOS.
• Redesigned navigation and gameplay systems for spatial computing input.
• Implemented hand-tracking controls and spatial UI.
• Built a replay system recording trick and navigation data.
• Optimized performance for VisionOS hardware and delivered post-launch updates.

A commercial match-3 mobile title with full meta-gameplay, economy systems, and live-ops release support across iOS and Android. Progression, economy, IAP, quests, dialogs, and leaderboard systems drive retention and monetization, alongside 3D character behavior and animation pipelines. The title shipped as a store-ready, performance-optimized build across both platforms.

• Led a meta-gameplay team of 3 developers and a technical artist.
• Designed the progression, economy, IAP, quest, and leaderboard systems.
• Built 3D character behavior systems and animation pipelines.
• Optimized iOS and Android performance for store release.

A match-3/city-builder mobile game combining a world map with isometric city-building, editor-driven content tools, async UI flows, social features, and third-party SDK integrations.

• Built the world-map and isometric city-builder systems.
• Developed internal editor tools and async UI systems.
• Integrated social features and third-party SDKs.
