Implemented Virtual Web Cam for the Mac desktop that inserted itself into the camera pipeline and allowed adding various post-processing effects on the fly for video conferencing applications such as Skype and Zoom.

通过蓝牙与医疗设备通信的iOS应用程序. The device is worn by the user as therapy and the app collects sensor data continuously and sends it up to the cloud for analysis.

A macOS app that uses computer vision to analyze video coming from a 3D camera (attached to the user's head) and detect motion and gestures of the hand positioned in front of the screen. The app enables the user to interact with the screen using their hand emulating a touchscreen. I used machine learning models for gesture recognition and OpenCV for motion tracking.

An iOS app that provides an intuitive UI for placing virtual furniture objects on floors/walls and ceilings. It uses an accelerometer to navigate through 3D models of rooms and walkways and gesture controls to attach the furniture to surfaces of the space.

一个个人理财应用程序，有一个非常时尚的UI. I developed the most essential components for the app to support complex user interactions and fluid animations and transitions. I helped prepare and file the app and was listed as co-inventor on the patent application for Vimvest's unique approach to personal financing.

A MacOS/iOS app combo that allows the user to navigate through a 180/360-degree video rendered on Mac by rotating an iPhone connected to Mac computer wirelessly, imitating rotation of the user's head. The video coming from the 180- or 360-degree camera is rendered on a curved 3D surface using SceneKit so that it looks as if you are looking around with your head in a real world.

An iOS app that enables the user to virtually "paint" a wall in their house by viewing through the iPhone camera how the wall would look like if it's painted with a chosen color. Uses ARKit to detect walls in the video feed coming from the camera and attach a virtual color swatch over the real wall taking into account lighting and other factors to make it look realistic. Used metal shaders for high performance rendering while performing complex calculations on every pixel to make the colors "mix" properly.

Snakt就像视频乐高:你看到的每一个视频都可以在你自己的帖子中重新利用. 包括你最喜欢的创作者和明星的数以百万计的动图、vine和帖子. Developed by me from scratch, the app offers a wide variety of sleek animations and gesture controls. Takes full advantage of AVFoundation for efficient and elaborate video editing right on the device.

一个iPad应用程序，可以帮助投票工作人员跟踪登记选民. 需要处理大量的记录, 在投票站内的多个ipad之间进行点对点同步, 与后端持续同步, scanning of licenses, printing of receipts on a portable printer, and many other futures. Fully customizable for any county, 包括外观和感觉，并适应不同的投票/注册规则. The app has been widely deployed all over the US and has processed millions of voter records to date.

Kasper将同一所大学的学生联系起来，帮助他们计划活动, 交换他们感兴趣的领域的信息, and trade learning courses, complete with real-time chat and messaging.

为Toptal的一个客户从零开始建造的. 帮助人们跟踪他们的健康选择和观察他们的卡路里摄入量.

This is an underwater adventure game.

US 8,386,316:授权远程访问视频资源的方法和系统
US 8,376,853:手持自定向瞄准游戏.

基于Swift的iOS应用程序，为照片和视频添加视觉效果和滤镜. 利用核心图像滤镜实现专业质量效果, 金属性能着色器和自定义金属着色器. Required a lot of creative thinking and domain knowledge to come up with the right approach or combination of approaches for each of the effects while keeping performance under control.

As a lead iOS developer, 我已经从头开始实现了应用程序的大部分功能, 包括使用Core Image和Metal的酷炫视觉效果. Almost single-handedly developed a full-fledged non-linear video editor as one of the app features, 允许将视频和照片拼接在一个时间轴上, adding effects, captions, music, and voice-over. 广泛使用AVFoundation进行实时预览和导出到相机胶卷.

一个拥有数百万用户的视频编辑和图像处理应用程序. I was the principal developer and primary contributor responsible for the overall architecture and the flagship features of the app. The features I worked on include real-time video processing using Core Image and Metal, 一个非线性多轨道视频编辑器，允许一个拼接在一起的视频, images, audio, voiceovers with effects and text overlays, 以及这个应用的其他功能.
