Built a Tic Tac Toe agent that is trained by Q learning Algorithm, being able to play against human player with a high winning rate and a 0 loss rate.

• Trained separate Q-tables for Player X and Player O.
• Optimized both Q-tables through self-play between 2 players X and O controlled by computer.

Typewriter

Built a text editor that is able to run within user's terminal, supports most of the functionality as a basic editor (e.g. moving cursor, adding/deleting contents, saving text etc).

• Used the Stack ADT for undo and redo functionality
• Extensively tested the "real world" edge cases (e.g. when the cursor is at top, bottom, left edge, right edge of the terminal)

Created a social website that matches users based on hobbies, location, and availability, then suggests group activities using AI.

• Aimed to address the growing sense of loneliness by enabling meaningful connections without requiring extensive personal information upfront.
• Tech stack: HTML/CSS/JavaScript · Node.js & Express · MongoDB Atlas · Claude (Anthropic)

Designed a time-series model based on a neural network to analyze large-scale urban transportation datasets and forecast future passenger flow using MATLAB, SPSS.

• Optimized neural network parameters (input–hidden weights, hidden/output thresholds) using a genetic algorithm to obtain globally optimal solutions.
• Incorporated feature engineering principles by selecting key variables (e.g. weather, temperature, and holiday indicators) from multi-factor datasets (e.g. anonymized metro trip records, station metadata, and user attributes).
