Full-Stack & Embedded Systems Developer · CS Student @ Université Ahmed Draia (M1 Intelligent Systems)
I'm a self-driven developer from Algeria who builds where the digital meets the physical. I specialize in the full stack — from clean, functional interfaces built on modern primitives like shadcn/ui, to bare-metal embedded systems logic running on microcontrollers in the field.
My foundation is in low-level systems and Rust, which instilled a "no-magic" approach to software. I don't just build apps; I build real-world products that ship — healthcare SaaS, driving school platforms, offline-first POS systems, fire detection models, and LoRa-based IoT infrastructure. I prioritize performance, maintainable architecture, and systems that don't break under pressure.
I also lead the Pioneers CS Club at my university and an Aerospace & Astronomy Club focused on rocket telemetry, drone search-and-rescue, and embedded hardware — bridging CS education with real engineering.
- 🔭 Currently shipping: MedLink (healthcare SaaS for Algeria) · DriveTrack (driving school platform) · Adrar Market POS (offline-first, Tauri + SQLite)
- 🌱 Exploring: Embassy async runtime on ESP32, distributed sync architectures, Arabic NLP
- 💬 Ask me about: Rust, Hono/Axum backends, Tauri desktop apps, LoRa embedded systems, or building production software as a student
- 🎯 Philosophy: Ship real products, not toy projects
- ⚡ Fun fact: I organized Hackathon AI Day Adrar 2026 and trained a YOLO fire detection model with 92–96% mAP@50 for the event
