Ahmed E.

I help founders and engineering teams turn embedded concepts into production-ready IoT products - not just prototypes. I’ve worked on commercial IoT devices deployed in the European Union, taking full ownership of firmware, PCB design, and wireless communication to ensure reliability, manufacturability, and long-term stability. What I specialize in ☑️ PCB Design & Hardware Ownership Single and multi-layer boards designed for manufacturing, testing, and deployment. ☑️ Firmware for Real Products Clean, maintainable C/C++ firmware for ESP32-based systems. ☑️ Production-Grade Communication UART, I2C, SPI, MQTT, HTTP, BLE, Wi-Fi, OTA, ESP-NOW — implemented with reliability in mind. ☑️ End-to-End IoT Systems From schematic and PCB to firmware, cloud integration, and field deployment. What you get when you work with me • Manufacturer-ready deliverables (BOM, Gerbers, Pick-and-Place) • BOM optimized for cost and regional availability • Design decisions based on real deployment experience • Clear communication and product-level thinking Background • Embedded Systems Engineer at a German IoT company • Top-Rated on Upwork with consistent 5-star feedback • Experience delivering multiple commercial IoT product lines If you need someone who understands what happens after the device ships, let’s talk. 📩 Available for consultation, fixes, or full product develop
