FOUNDER PORTFOLIO · BAYARBAYASGALAN ENKHTULGA
I build products that
investigate, teach,
protect, and create.
I'm BeBe / Nero_404 — a 15-year-old high-school builder from Darkhan, Mongolia. I work across practical AI, defensive security, product systems, computer vision, and robotics-oriented experiments.

01 / FEATURED PROJECTS
Show all projects →Three projects that best explain how I build.
HuruInk
A privacy-friendly browser experience where real-time hand gestures become drawing, erasing, pause, and undo controls.
Aura Guide
A four-direction obstacle-detection wearable with Bluetooth communication and Mongolian voice warnings for visually impaired users.
02 / BUILDER PATTERN
Project-first. Product-minded. Built to be judged by the work.
My older portfolio focused on one clear idea: real projects are the proof. That is still the core here. I build end-to-end — problem framing, interface, logic, backend boundaries, documentation, deployment, testing, and iteration — then keep the strongest work visible.
