Fun Fact
Most people don’t know that I once learned an entire programming language over a holiday break just for fun. I was curious about how machine learning models worked, so I spent two weeks diving into Python and built a small predictive model for fun.
Passion
What truly motivates me is the sense of accomplishment that comes from doing things well and seeing the impact of my work. I thrive on solving complex problems, improving processes, and delivering high-quality results.
