Applied Cryptographer specializing in privacy-enhancing technologies.
I am an Applied Cryptographer with a strong focus on designing privacy-enhancing systems and developing cryptographic frameworks for secure data processing. My expertise lies in data-in-use cryptography, searchable encryption, and homomorphic encryption, where I translate advanced cryptographic research into practical applications. I have a proven track record of leading cross-functional teams and ensuring compliance with data protection regulations, enhancing security through innovative privacy solutions.
Throughout my career, I have designed and implemented encrypted databases with searchable encryption and granular access controls. My experience includes optimizing protocols and integrating advanced privacy-enhancing technologies for secure data analytics. I have collaborated with various stakeholders to address privacy and security challenges, ensuring that our solutions are both effective and compliant with regulations such as GDPR and CCPA.
With a Master of Science in Computer Engineering and a Bachelor of Information Systems from the University of São Paulo, I am committed to advancing the field of cryptography and data security. I am passionate about developing scalable solutions that not only meet current demands but also anticipate future challenges in data privacy.
