FIN Finance

About Me

I'm an MBA with over years of investment experience. My career has spanned equity research, portfolio management, and market analysis across global financial markets.

Outside of finance, I've developed a passion for building software from scratch. I enjoy applying the same analytical and quantitative thinking from investing to writing code — whether it's game mechanics, data visualizations, or interactive web apps.

The projects on this site are things I've built for fun and learning, combining creativity with problem-solving. I'm always looking for new ideas to prototype and bring to life.
