I started programming when I was 10 years old out of curiosity because I wanted to create a site like the Cartoon Network website that I watched as a child. From that time I made a lot of things out of curiosity: A browser using Delphi; my first programming language and also a Wordpress-like system from scratch. I also created a dropbox-like system for internal networks with low internet speed, to share files with within my house. In 2015 I started working professionally at Pagar.me as a member of the founding team to build a “Stripe for Brazil”. Later I joined my co-founder Thiago Arnese as a CTO of Hash, and then we left to join CloudWalk to create the first DeFI lending product for SMBs in Brazil. The purpose of that project was to allow merchants to use DeFi without knowing about it. I’m also very interested in philanthropy, and hope to create as much impact as possible. I helped build a online school called Alpha Edtech: A non-profit organization that help people in vulnerable environments to learn programming fast to get a job at our partner companies and increase the quality of life of they family and inspire they community.

One of the hardest things I had to build that required creativity and perseverance was an algorithm to generate dukpt keys for POS manufacturers. They didn’t provide documentation and content online was almost inexistent. I had to resort to reverse engineering and research on Chinese forums. We also had a timeline of 1 week to go to the factory to create the cryptographic key to use for the POS. I was very anxious to know if I would be able to pull it off, but in the end, I was able to do it and made that algorithm open-source so that other people don’t have to pass through what I had. https://github.com/hashlab/dukptkit
