I began investing in 2005 while still in medical school. In 2007, I started trading on the Brazilian stock exchange. 

By 2008, I was investing in the forex market using automated robots. For many years, I saw good returns with my stock portfolio in Brazil. 

Through day and swing trading with robots in forex, I had excellent years and others not so much; my results were unstable, though I tended to win more than lose. 

In 2020, I started investing in cryptocurrencies with robots, and in 6 months, I turned $32,000 into over $1 million. I stopped trading and exited this market upon identifying the end of that bull market cycle. 

Also in 2020, I began to study macroeconomics in depth, which became part of my analysis process, using fundamentals in my analysis as well and keeping up with new technologies. This is how I identified opportunities in cryptocurrencies, recognizing a time when the macroeconomic scenario was favorable, blockchain was an emerging technology, and then I developed a portfolio strategy that had an edge in selecting cryptocurrencies. 

Nowadays, my strategy is focused on long/short in the US stock market, aiming to buy (long) the best stocks (usually large tech stocks with high growth potential, solid business moat, but also some excellent defensive stocks) or ETFs of the best sectors and sell (short) ETFs that have poor strategies and/or prospects.

I spent over a decade inside complex organizations—scaling teams, driving growth, and leading transformation across Fortune 100s, Big 4 firms, and high-growth ventures.

On paper, I was the definition of impact and performance...

But when transitioning from corporate to entrepreneurship, I faced a different kind of challenge—one no playbook had prepared me for.

Despite all my experience, I struggled...

- I tried to copy models that didn’t fit who I was.
- I doubted myself. Compared. Looped.
- Back and forth, over and over—I was exhausted.

And exhaustion wasn’t the life I wanted.
I wanted to love it all. To enjoy it all.

Until one day—I fell to my knees—and I finally saw it:

I was playing a game of Next Level Moves with rules I didn’t even understand.

I realized that to reach my next level, I had to go deeper—beyond strategy, beyond mindset, into identity, nervous system, heart, and soul.
I had to D.A.R.E to start designing life, business, and success on my own terms.

That’s how The Next Level Moves Method was born—built on my D.A.R.E. Framework:

1. Diagnose what blocks your Next Level signal.
2. Address what distorts it.
3. Rewire to broadcast it clean.
4. Embody so the signal is you.

This approach blends the precision of coaching, the depth of identity, the clarity of mindset, the release of healing, and the strength of a regulated nervous system—collapsing time and turning the impossible into inevitable.

Now, I work with visionary leaders ready to do it differently.
The rebels. The visionaries.
Those who refuse to live by default—and are ready to design success on their own terms.

I have three questions for you:

1. Do you D.A.R.E. to become your next level?
2. Can you afford not to become your next level?
3. Are you just curious—or serious about it all?

Welcome.
