Course Enrollment System
I am involved as a full-stack developer in the system that serves 1500+ students.
• Designed and created 5 tables in ​AWS RDS​ ​MySQL ​to allow teachers add/delete courses, students enroll/drop courses
• Programmed enrollment website with ​JavaScript​ via ​React​ using ​React Router​, ​React Hook​, and
Material UI​. Deployed on ​AWS S3 ​with static web hosting
• Built a back-end service using ​Java​-based ​Spring Boot​. Published docker image with ​Google jib​ to ​AWS Elastic Container Registry (ECR)
• Created and deployed dev & prod environment with 5 nodes each on ​AWS​ ​Elastic Kubernetes Service
(EKS) ​with ​Elastic Load Balancer ​integrated
• Introduced ​GitHub Action​ as ​Continuous Integration​ to reduce deployment time by 83%
• Configured and connected MySQL with ​Hibernate​. Implemented all back-end APIs with ​RESTful convention. Introduced​ JWT token​ using ​Spring Security​ and stored it as cookies in front-end

Online Comment Stream Processor
• Set u​p a data ingestion layer with internal live comment streaming API with ​Python
• Implemented a real-time comment processor with ​Apache ​Spark​ ​for live-streaming comments
• Introduced statistic ​chart for top 10 comments using ​Ajax​ long polling with 3s interval
• Deployed and configured ​Google Cloud Platform VM instance​ to support external viewing

Real Time Sentiment Analysis
• Built event queuing layer with ​​Kafka​​ to process input dataflow
• Implemented sentiment monitor with​ ​Apache Spark​​ capable of handling up to 60 comments per second
• Visualized real-time positive vs. negative sentiments trends using ​Python
• Created analytic dashboard using ​React ​to showcase different teachers’ popularity among online audience
• Helped advertisement team to analyze audience’s preference, which increased course income by 10% and new user registration by 30%

Low Power Environmental Sensing System
(Researcher under Prof. Bob Iannucci, CMU)
• Commissioned by United State Geological Survey (USGS) with million dollars of funding
• Developed a low-power wireless sensing system for collecting stream height data of Pepperwood Preserve, Sonoma County, California, achieved 10X battery life time extension with advance low power technology
• Enabled lower power communication between sensing systems and gateway via LoRa 
• Reduced the cost of 5+ rangers/year for monitoring the stream height manually
• Led a 4-engineer firmware team for this complicated system with 14 components
• Implemented firmware for 5 sensors with hardware interfaces​ UART​,​ I2C​ and ​SPI ​using​ C
• Used ​JTAG​, ​Logic Analyzer​ and​ Oscilloscope​ extensively
• Used ​Python​ to orchestrate transmitter and receiver for LoRa signal strength data collection

### Research Assistant @ UNSW
Jan 2017 – Jan 2018 | Sydney, Australia
Researcher under Prof. Vijay Sivaraman, UNSW                                                                         
• Managed a team of 4 engineering students to build a system that estimates the bus queue length, waiting time, and recommend the bus stop with shortest waiting time to users via mobile application
• Utilized Python and mySQL API to implement user and bus data acquisition, resulting in a backend flask server bridging between web/mobile application and databases for 5 real-time parameters
• Innovated the method of QR code scanning along the bus queue to track the queue length
