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 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, reading about LWC, and playing video games. Currently iterating on CipherLock, a hub for interactive cryptographic tool for education.

CipherLock v1.2 - share an encrypted message with a single link, now in 9 languages

CipherLock v1.2 is here. Same promise (encrypt and learn, 100% in your browser, no accounts, no tracking), with a lot of new things since launch.

SHARE AN ENCRYPTED MESSAGE WITH A LINK

Encrypt something, copy the link, send it. When the other person opens it, CipherLock fills the tool and reveals the message automatically, framed right where you can read it. The encrypted payload travels inside the URL fragment, so it never reaches any server. Native share sheet on mobile, WhatsApp and X on desktop, or just copy the link.
