- Discord BotDiscordJun 2025 - Current (1 year 4 months)As a personal project, I developed a custom Discord bot that connects to a web-based dashboard, combining both frontend and backend technologies. On the backend, I used Node.js with JavaScript/TypeScript, MongoDB for data storage, and Prisma as the ORM, integrating the Discord API to manage server events and user interactions. The frontend was built with React, HTML, and CSS to create an intuitive interface for managing the bot. I used Visual Studio Code for programming and Photoshop to edit and design custom images for both the interface and the bot's embedded messages. This project allowed me to gain practical experience working with APIs, asynchronous programming, databases, and full-stack development in a real-world setting.
