• 2018-2021 Archival Storage(HDD/Tape)

Scaling up HDD-based distributed storage system to support PB level daily throughput.

Build scalable Tape-base distributed storage system with high durability and disaster recovery capability to support low TCO next generation storage.

Designed and implemented network interface for connecting and communicating between different trackers and VR character.

Integrated and updated the interface between trackers and lower level hardware capture.

 Created an interactive real-time tempo-changing audio player in C++ to play tempo changeable music locally or under control of computerized “conductor”.

 Implemented real-time, multi-thread block processing in reading data, PV processing data and playing data.

 Generated two layers of beat mapping, which can transfer live beat into reference beat (uniform beat for different players),

and from reference beat to media beat (actual beat in music file)

 Mastered audio source libraries, including Portaudio, Libsndfile, wxWidgets, ZeroMQ and Phase Vocoder.
