Mohamed AhmedSystems Builder · AI / Embedded / Full-Stack Engineer
Undergraduate engineer driven by systems-level understanding. I build solutions crossing physical and digital boundaries—from bare-metal firmware (ESP32/STM32) and private mesh networking to local AI fine-tuning (QLoRA/Unsloth), PostgreSQL RLS architectures, and production desktop environments.
Building Systems Across the Full Spectrum
I am not simply a frontend developer or a high-level software engineer. As a Computer Engineering student at Cairo University, I design and build solutions across the physical and digital continuum.
I am a Computer Engineering undergraduate at Cairo University (Class of 2029) driven by systems-level understanding. Rather than confining myself to a single layer of the stack, I design and build solutions across hardware, firmware, distributed backends, local machine learning, and refined user interfaces.
My practical work spans bare-metal microcontrollers (ESP32, STM32, Arduino), embedded networking (MQTT, Tailscale mesh VPNs), local AI acceleration (QLoRA fine-tuning on RTX 4060, GGUF quantization, custom agent runtimes), and resilient software architectures (Next.js, FastAPI, PostgreSQL RLS, Tauri 2 with Rust).
I believe that great engineering happens at the intersections: where low-latency embedded telemetry meets intuitive cloud dashboards, where authoritative relational state eliminates conversational AI amnesia, and where rigorous security and resource constraints dictate lean, elegant code.
Authoritative State Over AI Hallucination
AI models must not operate as free-floating guessers. Robust architectures require strict relational databases as the authoritative ground truth of state; AI operates as the deterministic reasoning layer reading that verified memory.
Resource-Bounded Architecture
Software should thrive under tight hardware constraints. Systems should prioritize chunked streaming I/O, lean asynchronous runtimes, and bounded memory buffers to achieve maximum resilience on low-resource environments.
Provable Scarcity Without Web3 Bloat
Digital ownership can be verified cleanly through cryptography and relational invariants. FINITE achieves atomic serial allocation and offline desktop lease verification using Ed25519 and DPAPI without tokens or blockchains.
Observation ≠ Canonical Truth
In automated data extraction, a scraper failure is an observation, not ecosystem reality. In AI Radar, the Sentinel validation pipeline quarantines anomalous drops to prevent overwriting history with empty datasets.
