My Projects
A selection of my work.
Twitch Chat Bot
A Node.js bot that responded to chat commands on Twitch. It collected user data for contests, displayed live Bitcoin and Ethereum prices, and ran as a local desktop app with a console interface. Built with node-fetch, tmi.js, and axios.
2D RPG Game – The Fox
A 2D RPG created in Godot as a high school graduation project. The player controls a fox exploring the world. I handled all code, composed original music, and designed assets (with some external resources).
Stock Screener App (Team Project)
A React-based stock screener that fetched market data from a database, allowed filtering by multiple metrics, and visualized trends with charts. I was responsible for UX and various frontend features in the team project.
Electrostatic Field Visualization
Interactive C# WinForms application that visualized electrostatic fields as color maps and vector arrows. Users could modify charge positions, magnitudes, and rotation dynamically.
Networking Projects – TicTacToe & TCP Server
Python TicTacToe server allowing multiple rooms where users could join and play via a TCP protocol implementation. A separate C++ TCP server demonstrated custom protocol handling and network communication logic.
Mathematical Function Renderer (ANSI C)
ANSI C console application that rendered a user-defined mathematical function into a PostScript file using recursive descent parsing.
Custom Inode Filesystem
C++ implementation of a basic inode-based filesystem as a university project for an Operating Systems course. Supported core operations such as reading, writing, and managing directories and metadata.
