Big Data Engineer / System Engineer
Taipei City, Taiwan
• Built a real-time log streaming system using Graylog to track resource usage of each process in edge devices and setup alarms. Also built a dashboard for team members to view the monitored metrics.• Composed Linux scripts to help deploy face recognition model to edge devices, including environment configuration script, system startup script, and scheduled script.• Researched and implemented face anti-spoofing (liveness detection) from infrared (IR) and visible light (RGB) images. The method involves head post estimation and image quality assessment techniques.• Constructed a face verification system with C++ for NIST FRVT 1:1 Contest. And working with machine learning engineers to optimize the system’s performance and efficiency, including image pre-processing, tunning of face detection model, and post-processing of model output (vector quantization).
