About Me

I'm a Computer Science student at California State University Dominguez Hills with a focus on machine learning and data-driven software. My favorite project so far is an NFL player prediction system that consistently outperforms professional DFS platforms — it's the kind of problem where the right feature engineering and model tuning can make a real difference.

I got into CS after working in some pretty different fields — infrastructure projects at an electric company, healthcare, retail. Those experiences taught me how to manage complexity and communicate clearly, which turns out to be just as important in software as it is anywhere else.

Outside of code, I lead the worship band at House of the Lord where I play bass. I'm also usually at the gym, stargazing, or tinkering with a side project.

Here are a few technologies I've been working with recently:

  • ▹ Python
  • ▹ C++
  • ▹ Java
  • ▹ JavaScript (ES6+)
  • ▹ CatBoost / Scikit-learn
  • ▹ Pandas / NumPy
  • ▹ Node.js
