About

I’m a Computer Science student at UNICAP (Recife, Brazil) currently deep-diving into the foundations of cryptography for my final thesis. My focus is on turning complex, low-level concepts into beautiful, didactic, and functional digital experiences. I follow a "build-to-learn" philosophy. I believe the best way to master any architecture or algorithm is to engineer it from scratch. Outside of academia, I spend my time building SaaS platforms with themes that interest or motivate me, designing maps for tabletop RPGs, and playing Apex Legends. Currently iterating on CipherLock, a minimalist hub for interactive cryptographic education.
