Mar 2025 – Present · 1 yr 2 mos · Remote

➢ Designed & built lightweight Vulkan Compute Engine for running compute shaders on wide range of Android devices, in c++ and NDK, for IKEA’s single-view room scanning experience.
➢ Implemented real-time CPU & GPU video downsampling algorithms in c++ and Vulkan, using the Android NDK, to support video recording at lower frame-rate in AR Core.
➢ Designed and built lightweight integration test framework that enabled automated on-device regression testing of legacy room capture codebase to speed up R&D efforts.
➢ Developed various debug visualization tools for quickly inspecting quality of Android sensor data on a wide range of Android devices during R&D.
➢ Integrated AR Engine, a custom OpenGL renderer built for AR Core apps in Kotlin, from new R&D project into existing production capture flows.
➢ Prototyped multi-threaded floor-detection step in Kotlin and AR Core, with custom GLSL shaders for rendering floor-plane based on UI/UX designs.
➢ Prototyped out floor-rendering and world-space UI with vertex animation, 3D model loading & rendering capabilities in Kotlin + OpenGL / GLSL in AR Engine on Android.
➢ In last minute request, jumped onto real-time AR product visualization project to help improve and fix bugs in floor detection and 3D interactions in AR, using Sceneview Android, built on Google’s Filament renderer.
