Projects
ArdentChat
A real-time messaging application for one-on-one communication between 50 students and staff members
- Implemented the front-end with React.js so users can send text messages and receive media files such as GIF and PDF
- Communicated with the Atlas MongoDB service from an Express.js back end to store and manage user data
- Utilized Socket.IO to establish full-duplex instant connection between two parties of the of the communication
Fabflix
A Java EE web application with high scalability allowing customers to search and purchase over 20,000 movies under 500ms
- Synchronized the data between leader and follower MySQL databases by creating two load balancers to distribute the network traffic, trimming the response time from over 400ms to 100-200ms
- Integrated fuzzy search backed by the edit distance algorithm into the application while keeping the response time around 80ms
- Optimized data processing time from 25 minutes to 3 minutes for parsing over 70,000 entries using batch insert and a hash table
AntCatalog
A website enabling students in the University of California, Irvine to gain analytic insights on graduate courses starting from Summer 2013 to Fall 2022
- Applied the compression middleware to reduce the size of the largest payload from 5mb to 411kb
- Performed stress testing with Locust to ensure the correctness of data as well as well as the API service
- Programmed the rate limiting mechanism to allow maximum of 5 requests per second from the same source
- Configured the caching mechanism on the server to return the response under 100ms given the same request had been issued
ICS Search Engine
A search engine written in Python that was able to handle thousands of webpages under a subset of the UCI ICS domain with the query response time below 300ms
- Ranked the relevance among seven thousand pages in low response time by coding custom cosine similarity algorithm with tf-idf weighting
- Parsed the text within webpages to store them into an inverted index distributed among various small index files
- Constructed the search engine with 3 students in 4 weeks
