I help startups and companies turn ideas into reliable, production-ready electronic products — from first schematic to manufacturing floor. With 50+ completed projects, I deliver end-to-end embedded product development: system architecture, schematic design, high-speed PCB layout, embedded firmware, mechanical enclosure design, prototype validation, and manufacturing support. I work with early-stage startups needing a fast, solid MVP just as well as established companies needing production-grade, DFM-optimized designs. What I bring: Embedded hardware & firmware (STM32, ESP32, ARM Cortex-M, FreeRTOS, low-level drivers) High-speed & multilayer PCB design — signal/power integrity, EMI/EMC compliance Automotive & industrial electronics (CAN, LIN, RS485) Full product lifecycle: concept → schematic → PCB → firmware → prototype → manufacturing Tools: Altium Designer, KiCad, EasyEDA, STM32CubeIDE/CubeMX, ESP-IDF, LTspice, SolidWorks, Fusion 360 Whether you need a quick proof-of-concept or a fully validated production design, I can take your product from idea to reality. Let's build your next embedded product — send me a message and let's talk about your project.

Failed to follow instructions most of the time, complained a lot knowing all the requirements up front. I had asked for a 4 layer PCB, which he made. But it had no GND plane, no PWR (used a signal plane) that was barely used for some low voltage lines, there was very little consideration taken for track widths for specific Nets, specific size of the board or specific parts placement not used, the list now goes on. Lucky not to have sent for manufacturing, had to redo from scratch.

I worked with Mahmoud, and he delivered excellent work. In addition, he proposed and implemented new features. I highly recommend him to anyone considering working with him.
