Responsibilities include:

• Migrated and separated a JSP + Spring web application into two newly-constructed end-to-end services.
• Built the frontend in TypeScript with React/Katal, Redux and Saga on S3 and delivered static assets through CloudFront.
• Built the middle tier as an ARest service with Guice in Java on HEX-AWS, intended for fetching dependency metadata from DynamoDB and for propagating rectified requests & responses.
• Established two complete repository-to-prod deployment pipelines and integrated the fully-functional services with backend.
• Unit-tested all code with line coverage over 90% by using Jest and Enzyme for front end and Mockito for middle tier.

Responsibilities include:

• Built a multi-layer ROS map with regions and waypoints visualized in Arora based on TypeScript and React.
• Tracked and visualized body part motion trajectory in decaying pattern with Dynamic-Reconfiguration in ROS.
• Processed THÖR dataset to display multiple moving persons’ 3D point cloud and head orientation in real time.
• Reproduced part work of Bayesian Estimator for Partial Trajectory Alignment to train a model for behavior recognition.

Responsibilities include:

• Implemented C++ inference process of neural networks and improved code efficiency by 40% through Mobile AI Compute Engine.
• Deployed neural networks on mobile ARM platforms such as RK3399, Raspberry Pi and other SoCs.
• Developed a multi-thread fast video stabilization algorithm based on Kalman Filter and Gaussian Filter (Avg FPS: 149).
• Contrasted multiple human face detection algorithms’ performance (Dlib, libfacedetection, Arcsoft SDK, etc.) on ARMs.

Responsibilities include:

• Researched on omni-directional copters to decouple the relation between multi-copters’ posture and movement.
• Proposed collectively a novel flight control algorithm based on quarternion theory and 8 spatial vectors.
• Produced an indoor Octocopter with cubic carbon fiber frame and 8 aerial brushless motors capable of reverse rotation.
• Achieved highly-precise indoor localization and long-time spot hovering without floating by using Pozyx platform.
