I'm engineer Embedded Systems · Security · Low-Level Engineering

I build things at the intersection of hardware and software — where electrons meet instructions, and where security is not optional.

• 🦀 Systems engineer: Rust, C, Go — close to the metal, close to the kernel.
• 🐧 7+ years with Linux — from kernel modules and device drivers to Yocto builds and system hardening.
• 🔐 Information Security background (degree in IT security) — currently deepening offensive/embedded security.
• 🔧 Embedded & robotics enthusiast — firmware, PCB design, real-time systems, and things that move.
• 🧠 Exploring Edge AI / TinyML — deploying neural networks on constrained hardware.
• 🛡️ Building a CTF platform from scratch — backend, infrastructure, challenge engine.

**Embedded Linux Security

• Secure boot chains (U-Boot, TrustZone, OP-TEE)
• Firmware hardening & reverse engineering
• OTA update infrastructure & fleet security
• Safety-critical systems (IEC 62443, ISO 21434)

Systems Programming

• Bare-metal & RTOS firmware (Rust, C)
• Linux kernel modules & device drivers
• Performance-critical, memory-constrained code
• Cross-compilation & embedded CI/CD (HIL testing)

Security Tooling & Backend

• CTF platform development (Rust/Go backend)
• Challenge sandboxing & isolation
• Secure API design, auth, hardened infrastructure
• If I build backend — I build it like it's under attack

Edge AI

• ML inference on MCUs (TFLite Micro, CMSIS-NN)
• Model quantization & optimization for embedded
• Sensor fusion & on-device intelligence**

"We are not meant to adapt to the world — we are meant to redefine it."

The next frontier is not in the cloud — it's at the edge. Billions of devices that sense, decide, and act autonomously. They need to be fast, secure, and intelligent. That's what I build toward.

🧭 The code that matters most runs where there's no cloud to fall back on. 🧭 Code is the language of gods. My mission is to evolve with it.
