• Software Architect

  • Apr 2022 - Present

  Working as software architect for several software development teams (each team has 3-4 people) in AR/VR related technology development project in R&D department. My main focus is designing the whole software stack for prototyping and its optimization especially related to its throughput and latency. The key technologies are: - Graphics (DirectX12/Vulkan) - Computer visions (depth sensing, VSLAM) - Game engines (Unreal Engine 5) - Distributed and Parallel programing on PC(Windows) and on Cloud(Linux with GPU) Show less

  Working as software architect for several software development teams (each team has 3-4 people) who involved in the 4K VR-HMD prototype development project in R&D department. Some outcomes from this project was exhibited to public in the attached video:My main focus was to design the whole system software stack and help its implementation in detail to work the pipeline from sensors-to-display with maximum throughput and minimum latency. The key technologies are: - 3D Graphics (DirectX12) - Computer visions (VSLAM, depth sensing) - Game engines (Unreal Engine 4) - Windows system programming (including kernel-mode dervers for FPGAs) Show less
