Welcome

Welcome to my corner of the internet. I’m Youn Jae Kim, a software engineer who enjoys building interactive web applications and exploring the intersection of AI and software development.

What I’m Working On

Currently, I’m focused on a few key projects:

Arena Shooter Portal

A multiplayer browser-based shooter game at aagusportal.com. Built with Django, Three.js, and WebSockets for real-time gameplay. The interesting part? The AI opponents are trained using reinforcement learning with PyTorch and Stable-Baselines3.

Timmy the Whale

An AI chatbot with a friendly whale personality at timmythewhale.com. It uses fine-tuned language models to create engaging conversations while maintaining a consistent character.

Tech Stack

For those curious about how things are built:

  • Backend: Python, Django, FastAPI
  • Frontend: JavaScript, React, Vue, Three.js
  • AI/ML: PyTorch, Transformers, Stable-Baselines3
  • Infrastructure: Docker, Kubernetes, Helm

What’s Next

I’ll be sharing more about:

  • Building real-time multiplayer games with WebSockets
  • Training AI agents using reinforcement learning
  • Deploying applications on Kubernetes
  • Random thoughts on software engineering

Stay tuned.
