Hey, I'm a

Backend & AI Developer.

Great systems should feel invisible. I'm Katia — third-year CS engineer at ESI-SBA and co-founder of BlindEYE, building REST APIs, AI pipelines, and the hardware they run on.

Who's AIT RAHMOUNE KATIA

AI Engineer by degree, builder by habit.

I'm in my fourth year of a Computer Science engineering degree at ESI-SBA in Algeria, focused on backend development and AI-powered applications. Most of my work lives in Node.js and Express — REST APIs, authentication, role-based access, real-time features — backed by PostgreSQL, MySQL, or MongoDB depending on the problem.

I focus on solving complex engineering problems, designing scalable systems, and building secure, reliable backend infrastructure. My strengths lie in software architecture, cloud technologies, system security, and turning ideas into production-ready solutions.

I co-founded BlindEYE to put that focus to use on something that matters: assistive hardware for people who don't have time for software that almost works.

Systems I've shipped.

Every project below got the same job from me: backend, data, and — where noted — the AI or hardware layer underneath. Web app, mobile app, or backend-only, tagged honestly.
