I build secure systems — from the Linux kernel to the browser.

A short readout.
01I graduated from New Bulgarian University and spent years as a Linux Administrator at DXC Bulgaria — keeping production Linux, networks, databases and virtualization running at scale.
02Today I work across the whole stack: low-level systems in C++ and Python, full-stack web with the MERN stack, Django and FastAPI, all wired together with Docker and KVM.
03I care about cybersecurity, clean architecture and the mathematics underneath. Strong DSA and problem-solving are the constant beneath every project — increasingly with AI in the loop.
