About Me
Profile · Philosophy

Computer Science bachelor at UNIRITTER university, focused on building resilient and efficient systems.

My path has been shaped by solving real problems in low-infrastructure environments, where I learned where I learned to translate complex demands into stable production environments, maintaining end-to-end technical integrity.

Differentiating factor: a historical return of 300% of the CDI in variable income investments, using a methodology that combines fundamental analysis with geopolitical intelligence.

I view the market as a dynamic ecosystem where geopolitical shifts and behavioral psychology drive volatility, but objective supply-and-demand analysis dictates long-term value.
