About Me

I’m a founder, business builder, and investment-focused professional interested in one thing above all: building and owning valuable businesses.

My interests sit at the intersection of entrepreneurship, investing, financial markets, technology, and business strategy.

I spend my time studying businesses, analyzing markets, researching investment opportunities, and building ventures from the ground up.

Long term, I’m building toward becoming an operator-investor — someone who can identify opportunities, deploy capital, build businesses, and create long-term value.

My approach is simple

  1. 01Learn
  2. 02Analyze
  3. 03Build
  4. 04Invest

Investing & Markets

Understanding businesses. Allocating capital. Thinking long term.

I approach markets the same way I approach building: study the underlying business, think in years rather than quarters, and treat capital allocation as a craft. My focus is on long-term ownership of productive assets — not speculation.
