Hire the Best Embedded Linux Specialists
in Egypt

I have been working in the field of embedded systems for about 10 yrs. With embedded systems, i mean both Microcontrollers and application processors that are used to build Single Board Computers (SBC). I have worked with many microcontrollers like PIC, AVR, STM32F1xx, STM32F2xx, STM32F4xx, STM32F0xx, LPC1768, TIVA-C, MSP430, OMAP l138, ESP32, ESP8266 and DA1458x. Also, i depend in many projects on SBC like raspberry pi, beagle board, orange pi, nano pi and tiny rex. I can use multiple languages for programming according to the platform used in the project. I have a great experience in programming with C, C++, embedded C, python, bash and perl. In addition to the field of embedded systems, i am very curious with security in any project i work in. I have a master degree in Cryptography in broadcast encryption. I tries always to follow security mechanisms in my solutions. I can afford security solution for the projects to keep data safe from unauthorized disclosure specially in network projects or projects that requires TCP communication.

Your prototype works on the bench. The first time a real customer plugs it in, it falls over — Wi-Fi setup fails, the firmware locks up after a week, the battery dies in three days instead of three months. That's the gap I close. I'm an embedded systems and IoT engineer. I take connected devices from "it works for me" to "it ships to customers and survives in the field." Most of my work falls into three areas: Embedded firmware on ESP32, STM32, nRF52, RP2040, AVR, and Raspberry Pi. C/C++ and Python. FreeRTOS and bare-metal. Low-power design when battery life matters — pushing sleep currents into single-digit µA, debugging the wake-up paths, tracking down the rogue peripheral that's keeping your device awake. Connectivity across BLE, Wi-Fi, MQTT, LoRa, LTE-M, NB-IoT, CAN, RS-485. Consumer IoT and headless devices. Captive-portal Wi-Fi onboarding so a non-technical customer can set up the device from their phone. Systemd watchdog services that recover from network drops automatically. OTA update infrastructure for fleet deployment. SD card write minimization on Linux-based devices, because the field failure mode no one warns you about is filesystem corruption six months in. PCB design when the project needs it. 2 to 8 layer boards in KiCad and Eagle, IPC-2221/7351 compliant. DFM and DFT review baked in from the schematic stage. Signal integrity, RF layout, and the kind of board-level decisions that affect yield, cost, and certification much more than firmware ever will. A few things worth knowing about how I work: I'm honest about scope. If your project doesn't need a custom PCB, cloud infrastructure, or edge ML, I'll tell you. I'd rather build the right thing for your actual budget than oversell. I think about the device's whole life, not just the demo. SD card longevity, Wi-Fi recovery, what happens when your customer's router changes, what happens when the firmware bug shows up in month six. The failure modes that matter are rarely the ones that show up on day one. I document for the human who comes after me. The setup guides and handoff docs I write are aimed at a non-technical reader — your future self, your in-house team, or whoever takes ownership when the contract closes. If you're building a connected device and the path from working prototype to shipping product isn't obvious yet, send me a message with what you're working on. I'll tell you honestly whether I can help.

I am a computer science student with extensive background in iot security and networking, I’m head of IEEE security branch in PUA, an excellent communicator and I’m extremely dedicated when I join a project. My skills include excellent communication and documentation, I can write academical papers with ease, as evidenced by my IELTS grade. I adhere to agreed upon prices and usually don’t charge per hour. I won’t take a job unless I can guarantee I can do it, additionally, if you’ve found yourself in need of a quick learner that’s where I shine the most. I’ve developed my own PoS system forked from ospos and currently working on integrating it with odoo for seamless integration without fully migrating to odoo. Excellent with wuick scripts, dirty work and the like- if you are on a budget and would like to keep the spendings to a minimum, I’m sure we can come to an agreement, just don’t hesitate to hit me up! I mostly love hardware hacking and projects concerning dumb workarounds, because I can more often than not transform that system into a robust, production-ready solution, just point me towards the system and watch the magic occur! I have designed many dev boards for rpi 3 and 4 compute modules, so evidently electrical engineering is something I excel at aswell. Especially IoT and embedded systems, and my projects do speak on my behalf. I’ve helped port openwrt to many unsupported systems, including modifying original firmware, modifying bootloader, patching drivers, etc I’ve also helped migrate an ERP system off the cloud to local hosting hardware while maintaining reliability and uptime. I have joined numerous championships, scoring second twice consecutively in WRO, locally and worldwide. Contribute to gadgetbridge huawei ble link v1 protocol reverse engineering. Also added support for storage manipulation. Enabled nfc functionality, but development stopped before fully understanding the payment process protocol. Basically the Swiss army knife of computer and through leisure before profession, but the best trademan you could hire is one who enjoys his work. If I applied, this means I’m interested, and therefore currently free, so please don’t hesitate to reply anytime, I’m almost always available.
