I design and build embedded hardware and firmware for connected devices — from schematic capture and PCB layout through firmware bring-up and field deployment. My background is mechatronics engineering with hands-on production experience leading hardware R&D for an industrial client. Embedded hardware and firmware: ESP32 and STM32 based designs, schematic capture and PCB layout/review in KiCad, component selection and BOM development, sensor integration (NFC, RFID, IMU, analog front-ends), and communication protocols including UART, SPI, I2C, Wi-Fi, MQTT, and BLE. I take projects from concept through Gerbers, prototyping, and manufacturing handoff. Currently leading hardware R&D as a Team Lead at an energy company, where I developed an NFC-based fuel transaction reader that cut fraud by 30 percent, and led hardware validation work that reduced terminal maintenance costs by over 70 percent. Beyond hardware, I also build the software layer around embedded systems when a project calls for it: Python/FastAPI backends, REST APIs, and AI-assisted tools such as document Q&A systems, so I can support a full device-to-dashboard build if needed. I deliver structured, documented work — schematics, Gerbers, BOM, and test notes — ready for manufacturing or continued development.

I deliver complete IoT and BLE product solutions — from schematic and PCB design through embedded firmware to Android companion apps. With 17+ completed Upwork projects, 100% Job Success Score, and 5-star reviews, I specialize in turning hardware concepts into production-ready designs. What I deliver: ✓ PCB Design: Schematic capture, multilayer PCB layout, BOM, Gerber files (Altium Designer) ✓ Embedded Firmware: BLE connectivity, sensor integration, motor control (ESP32, PIC32, STM32, Arduino) ✓ Android Apps: BLE companion apps for IoT device control, monitoring, and data logging My clients come back because I handle the full stack — no need to coordinate between separate hardware and software freelancers. Fast turnaround, clean documentation, and reliable communication. How I work: I respond within a few hours during Cairo business hours, confirm scope before starting, and break fixed-price projects into milestones so you always know what is coming next. Reviews mention "quick", "honest", "professional", and "committed to quality" - that is the working style I will bring to your project. Ready to talk? Send a message describing what you want to build. If you already have a schematic, datasheets, or a competitor teardown, include them - I will come back with a scoped milestone plan, not a generic pitch.
