I’m Hamza a Biomedical Engineer with a passion for Embedded Systems, IoT, Electronics, and Robotics. I turn ideas into real, working prototypes and products. Whether it’s designing smart devices, building automation systems, or creating medical technology, I bring innovation to life. What I Do Best: Embedded Systems & IoT Experience with ESP32, NRF52, ATMEL, STM32, PSOC, PIC Work with Raspberry Pi, VisionFive (Linux Board), and Unihiker Programming Proficient in C/C++, Python, Java, MATLAB, JavaScript, and Flutter Connectivity & Communication Skilled in UART, I2C, SPI, MQTT, BLE, BLE Mesh, Sigfox, and Wi-Fi Hardware Design & Prototyping Specialize in PCB Design, 3D Modeling, and Product Prototyping GUI Development Develop Touchscreen Interfaces, E-Paper & TFT Displays, Web Dashboards, and Desktop Applications Work with LVGL, Tkinter, PyQt, and Kivy Framework IoT & Cloud Integration Experienced with AWS IoT, Firebase, ThingsBoard, and WebSocket-based real-time control Industrial IoT (IIoT) Expertise in CAN Communication, Factory Automation, and Smart Sensor Networks Remote Monitoring & OTA Updates Work with ESP-IDF OTA, BLE DFU, and Cloud-Based Device Management I’ve built industrial prototypes, smart sensors, automation systems, and medical devices, real-time data processing and device connectivity. If you need a reliable, high-quality solution, let’s make it happen! Let’s Collaborate!

I build things that exist in the physical world — embedded systems, robotic mechanisms, IoT devices, and hardware prototypes that go from sketch to functional product. With hands-on experience across ESP32, Raspberry Pi, Arduino, STM32, and RTOS-based systems, I work the full hardware stack: firmware, sensor integration, CAD enclosure design in Fusion 360, FDM 3D printing, and PCB layout. I've shipped across domains — rehabilitation robotics, predictive maintenance, food safety sensing, animatronics, and industrial IoT. Currently a Product R&D Intern at Xibotix (building rehab devices and animatronic systems) and previously at Dotworld Technologies, where I delivered real-time actuator control systems end-to-end — from firmware to deployment. I work best with startups that have an idea but need someone who can build it. I don't just write code — I think about the enclosure, the power architecture, the sensor placement, and what failure looks like at 3 AM. That's the difference between a demo and a product.
