An interactive AR character experience built with Swift and RealityKit. As Lead iOS Engineer, I developed custom character controls, gesture interactions, physics integration, and rendering effects to bring virtual characters to the real world.

A visionOS Swift package that adds drag, rotate, scale, and surface-snapping gestures to RealityKit entities since the system gestures did not give enough control.

I built a native iOS app using Swift, Metal, and RoomPlan to scan entire homes, generate floor plans, and capture spatial data for 360° panoramas and Gaussian splatting. Developed custom shaders for real-time scan feedback and prototyped on-device mesh texturing before shifting to a cloud-based reconstruction pipeline

This App Clip + App combo allowed people to view their NFT's in AR. This was an immersive AR art experience built with Swift and RealityKit, featuring custom shaders, intuitive spatial interactions, location-based unlocks, and instant access through App Clips. Each artwork could carry spatial audio that stayed locked to the piece as you moved around it. Haptics confirmed scale snaps, placement, and capture, with Core Haptics patterns for longer transitions. Photos and video of the AR scene could be saved or shared with the artwork’s title and link.

I realized that with 2D hand tracking from Apple's Vision framework, and a depth buffer from ARKit, I could generate 3D hand tracking without relying on a 3rd party ML model.

Built real-time 3D AI characters with distinct personalities that can see, speak, and remember you, bringing immersive, interactive experiences to mobile.

An open-source Swift package that makes body, hand, face, and eye tracking easier to integrate into ARKit and RealityKit apps.

Twaddle is a language-learning app I designed and built to help learners develop real-world conversation skills through cognitive science-backed exercises, AI pronunciation feedback, and spaced repetition.

This was an immersive AR art experience built with Swift and RealityKit, featuring custom shaders, intuitive spatial interactions and a custom voiceover from a real world astronaut.

An AR shooter game for iOS

A spatial drawing app that lets users paint directly onto real-world surfaces using either their hands or the Logitech Muse spatial stylus. Powered by a custom BVH-accelerated ray casting library, PixelCastKit, that achieved sub-millisecond ray casts in testing.

A visionOS tower defense game played with the hands.

This enables multi-user AR with Multipeer Connectivity, RealityKit synchronization, and an ARKit collaborative session.

An iOS app that uses ARKit, Core ML, and RealityKit to detect objects in the camera feed and pin persistent 3D labels in the real world.

Experimenting with Metal Shaders to achieve desired effects

An open-source Swift package that simplifies RealityKit development with reusable utilities and convenience APIs for working with 3D entities, components, and resources.

Captured image mapping effect makes it look like the real world environment is distorting.

An open-source Swift package for defining RealityKit collision groups and assigning collision filters, including collisions with the LiDAR scene mesh.

An open-source Swift package for fading RealityKit entities in and out across Apple platforms, with OpacityComponent support and material-blending fallbacks for older systems.

An interactive augmented reality football game built for iOS using Swift, ARKit, and RealityKit. Players flick a virtual football through goalposts placed in their real-world environment, combining intuitive swipe controls with immersive AR gameplay.

A relaxing 2D mini golf game built with Unity, featuring satisfying physics, playful animations, immersive audio, and carefully crafted haptic feedback. Designed to make every shot feel great.

A festive 2D platformer built with Swift and SpriteKit. Run, jump, and collect acorns as a Christmas-hat-wearing squirrel, with smooth animations, responsive controls, and charming winter visuals.
