Hi there, I'm Mohammed Kotbi (Shadow Of Leaf) 👋

Full-Stack Developer | Systems Engineer | Tech Explorer

🚀 About Me

I'm a passionate Full-Stack Software Engineer based in Casablanca, Morocco. I thrive at the intersection of sleek, high-performance web applications and hardcore, low-level system internals.

On the Web, I architect and deliver complete end-to-end solutions. From crafting immersive, interactive frontends (like the PS3 XMB Portfolio) using React and Next.js, to designing robust, scalable backends with Node.js and Express (like the GreenVille Ecommerce platform and GitDocufy automation tool).

Under the hood, my love for Systems & OS drives me to push boundaries. I build custom Android ROMs and Linux kernels (bringing modern Android to legacy devices like the Lumia 950 XL), and I hack directly on the V8 JavaScript Engine and Node.js core to implement native multithreading capabilities from scratch.

✨ What I do:
- 🌐 Full-Stack Web: React, Next.js, Node.js, Express, MongoDB.
- ⚙️ Low-Level Systems: C/C++, V8 Engine internals, Custom Node.js runtimes.
- 📱 Android & Linux: Kernel development, Device Trees, LineageOS porting.
- 🛠️ Automation & Tools: Chrome Extensions, CI/CD, Scripting.
- 🎮 Gaming geek, PC builder, and relentless tinkerer.
