A bit about me
I am a developer focused on Backend with a particular passion for mathematics and cryptography. I am currently studying and applying complex cryptography concepts in projects such as an end-to-end encrypted chat system.
My interests range from security protocols like X3DH and Double Ratchet to systems automation and low-level tool development in C++. I believe mathematics is the universal language — and code is how we translate it into the real world.
