Used C, assembly, Linux kernel design patterns to build a demo multi-tasking OS Kernel that has an interactive shell, FAT16 file system, with the ability of memory management, paging, interrupt, crash-handling, ELF-files loading.
Created a News forum with user authentication, file-uploading by GridFS, account administration, content management with Spring-Cloud.

Deployed on AWS EC2 with Docker and used JMeter for load testing. Utilized AWS ELB to improve the throughput by 90%, to over 1800/s, and p99 response time under 100ms.
3D Facial Reconstruction Application
Developed an interface of a machine learning reconstruction algorithm by WebGL and React.js that renders the JSON 3D data based on the object illumination patterns with the provided 2D facial images.Accelerated the application by over 40% from implementing an observation-distance based multi-level rendering.
