Hello! 👋
I'm Youssef Achour
Python backend, AI & Tauri app developer
I design APIs, databases and complete products, from the server to the interface. I founded Cuik, an SEO platform, and I co-founded Magistral, an app that puts AI to work on your computer.
About
I'm a full-stack developer who specialises in the backend. I build systems that hold up under load: Python APIs, data processing, AI integrations and desktop apps.
I like taking a product from idea to production and handling everything in between: architecture, database, interface and servers. That's what I do every day on Cuik and Magistral.
