 About

I am a technology professional with global experience in open-source software, technology consulting, research, and education. As a pioneer and early advocate in the Brazilian blockchain ecosystem, I have been actively studying, teaching, and speaking on transformative technologies since 2013.

My academic foundation includes a Bachelor's in Business Administration (2015) and an MBA in IT Management (2022) from FGV, complemented by specialized training at the University of Cambridge (2010). Currently pursuing a Postgraduate Degree in Software Engineering at PUC-Rio (2026), I am focusing my technical expertise on Python, Linux environments, and Open Source development.

This educational background has enabled me to bridge the gap between cutting-edge innovation and practical, real-world applications throughout my career. As a Co-Founder of Hathor Network, I helped develop a groundbreaking Layer-1 blockchain with a novel architecture addressing scalability and decentralization challenges. My entrepreneurial journey continued as Head of Research at [web/lock], a Blockchain-as-a-Service company, and currently as Co-Founder of Via Chaplin, an entertainment financing startup that leverages emerging technologies to transform content funding and audience engagement.

My research credentials include roles at prestigious institutions: leading projects at the Institute for Technology and Society of Rio de Janeiro (ITS Rio) and Fundação Getulio Vargas (FGV), and serving as Head of Research at QR Capital.

Currently, I serve as Senior Blockchain Researcher at Instituto ECOA, PUC-Rio's multidisciplinary research, development, and innovation hub linked to the Vice-Rectorate for Development and Innovation (VRDI), where I contribute to applied R&D projects exploring distributed ledger technologies and emerging digital paradigms in partnership with industry and society.
