I’m an engineer based in Bahrain who lives at the intersection of physical reality and digital systems.
Most software developers joke about breaking production on Friday afternoon. Coming from high-voltage electrical engineering and fire-life-safety systems, my definition of "breaking production" involves real sparks, industrial alarms, and explaining things to Civil Defense inspectors. That background gave me a zero-failure mindset—whether I’m commissioning safety systems for multi-billion dollar industrial plants or handcrafting memory-safe concurrent backends.

- 🦀 The Systems Geek: Curious enough to write a single-threaded non-blocking HTTP web server in pure Rust with raw
libcsyscalls (epoll/kqueue), a 3D raytracer without graphics libraries, and an in-house Virtual DOM framework because "I want to know how it actually works under the hood." - 🐹 The Concurrency Fan: Hooked on Go goroutines, channels, deterministic event loops, and building real-time apps that don't choke under 1,000+ simultaneous connections.
- 🍵 Operational Truth: 90% tea, 10% pure refusal to leave a memory leak unresolved.
