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.

As the Economic Development Chair at U-District Partnership, a non-profit organization, my role focused on fostering the growth of small businesses within our community and ensuring their voices were heard.

In collaboration with the staff, I worked diligently to understand the unique challenges faced by these businesses. Using this knowledge, I advised the team on innovative and practical solutions to support their success and sustainability. One of my key initiatives was piloting grant programs with the City of Seattle to enhance public safety, underlining our commitment to creating a safe and conducive environment for businesses to thrive.

A significant aspect of my role involved connecting with small business owners and community members directly. I gathered their feedback and used it to guide our actions, always with the aim of enhancing the safety, economy, and development of the U-District.

President of the Board of Directors

ANEW

During my time as an intern at Anew Developers, a firm specializing in luxury micro-apartment developments, I gained invaluable experience and knowledge about the real estate development industry.

Each week, I had the opportunity to attend meetings with contractors, architects, and developers, which allowed me to gain a robust understanding of the inner workings of development projects. I was exposed to the complex interplay between different stakeholders and learned how to effectively communicate and collaborate within this dynamic environment.

A critical aspect of my internship involved learning about city codes and building requirements for new developments. I familiarized myself with the legal and regulatory landscape of real estate development, gaining a solid understanding of the necessary compliance requirements for building projects. This knowledge has since proven essential in navigating the complex world of property development.

In addition, I delved into the financial side of real estate, learning the basics of calculating Return on Investment (ROI) from various angles, including building costs and rental management. This exposure enabled me to understand the key financial metrics that drive profitable real estate projects.

Furthermore, I was tasked with conducting preliminary property research to assess whether the cost of development justified the property price. This hands-on experience not only honed my analytical skills but also helped me grasp the importance of diligent property evaluation in real estate development.
