Hi, I'm Hexi Wang

10th Grade Student | ML/AI Developer | Game Dev Enthusiast

Building AI-powered NPCs, exploring machine learning, and learning systems programming. Currently working on Gemma3NPC and busy with Kaggle Competitions.

About Me

I'm a 10th grader passionate about machine learning, game development, and systems programming. I also participate in Kaggle Hackathons with my friend, it feels really accomplishing after I finish one, regardless of the final result.

Current Focus

  • Gemma3NPC: Developing AI models for dynamic NPC interactions in games
  • RNA Folding: Standford's RNA folding challenge on Kaggle
  • FTC Robotics: Programming team member (Team 27589)
  • Unity & C#: Learning game development for future projects

Technical Skills

Python Java C Machine Learning LLMs Unsloth Tunix Unity (Learning)

Featured Projects

Gemma3NPC

Active

AI-powered NPC interaction system designed to be embedded in video games. Working on improving model performance, gathering & creating quality training data, for real-time character interactions. I hope to make a Unity game with dynamic NPCs.

Python Machine Learning LLMs

RAG Chatbot

Set Aside

A small RAG Chatbot I built using LangChain(v0.3), FastAPI and Streamlit during freshman year. My first "large scale" project, taught me a lot about software development. Set aside for now since I have more important projects than re-writing an old project.

Python AI LLMs

TunixHack

Completed

Me and my friend's submission for Google's Tunix Hackathon. Teaching Gemma3-1b to reason using Tunix (TPU Native LLM post-trining library) is some new exeperience. We learned a lot about Reinforment Learning, GRPO, reward function design and a lot of other weird issues one might encounter while training an LLM.

Python AI LLMs

Translator

Completed

A translator TUI APP I made to easily translate txt files using Textual and LM Studio. Another one of those times where I dedicated a month to make random thing.
