Project History
Job Skills Dashboard
https://github.com/uliang/JobSkillsDashboardA data visualization dashboard that displayed job market data on skills and hiring requirement trends. The analytics used a novel clustering method based on topic modeling to find clusters of skills, enabling the design and development of a more effective training course. I was the main analyst on the project leading a team of student interns to develop the dashboard and perform the data wrangling. The final dashboard solution consisted of Docker containers hosting a web API and React-based front end.
Natural Language Querying System
https://github.com/uliang/NaturalLanguageQueryingSystemA Django-based chatbot application that is developed from the ground up. The application collects natural language queries from users and translates them into search parameters to retrieve onboarding information from HR-related FAQs. The application is based on a spaCy model pipeline and uses word vector embeddings to power the chatbot. I was the lead developer of the application and the data scientist working on training the model.
Pygame Experiment: Tetris
https://github.com/uliang/PygameExperimentI wrote a Tetris clone using the reactive programming library Rx and SDL wrapping library Pygame to teach myself reactive programming and basic game development. It allows one to play the game of Tetris.
