⭐ 3+ years previous Embedded freelancing experience on fiverr with an avg. 5.0 Rating, served over 100+ clients and over 150+ projects sucessfully delivered. ⭐ 6+ years of commercial expertise in creating Embedded Hardware & PCB Design solutions. Hello, I am Mobeen, helping startups, engineers, and businesses turn their ideas into reliable, production-ready embedded products. I handle the complete development process from custom hardware and multilayer PCB design to firmware, and prototype validation. My Experience Covers: ✅ Microcontrollers (MCU) --- ESP32 , STM32 , ATMega , nRF ✅ System On Module (SoM) - Raspberry Pi , i.MX8 , Radxa , NVIDIA Jetson , Orange Pi , Banana Pi ✅ Cellular Modules ----------- SIMCom , Quectel , UBlox , LoRAWAN ✅ Power Electronics --------- Switch Mode Power Supply (SMPS) , AC/DC-DC Converters , Inverters ✅ Analog Audio --------------- Power Amplifiers (Class AB/ D) , Audio Filters , Pre-Amplfiiers , Audio Mixer COMMUNICATION PROTOCOLS: ✅ Microcontroller Level ------ I2C , SPI , UART , USB , I2S , CAN , RS232 , RS485 , MODBUS , LIN ✅ Internet Level --------------- Ethernet , TCP/IP , UDP , HTTP , MQTT ✅ Wireless Level -------------- Bluetooth/BLE , Wi-Fi , LoRA , NFC , LTE-M , NB-IoT , 4G/5G ✅ High-speed Level ---------- USB2.0/USB3.X , SDIO , eMMC , PCIe , MIPI CSI/DSI , SATA DESIGN SOFTWARE: ✅ Altium Designer ✅ EasyEDA Standard If you are starting from an idea, improving an existing design, or preparing a prototype for production, my focus is to identify technical challenges early, optimize cost and reliability, and deliver a solution that is ready for real-world use. I mostly order prototypes through JLCPCB, and with my experience in PCB manufacturing, I can also help optimize your PCBA costs. By carefully selecting components that avoid unnecessary handling and assembly fees, I can potentially reduce PCBA costs by up to 60% without compromising performance or reliability. I believe every successful project starts with an open discussion to fully understand the requirements before any design work begins. I will be looking forward for your short message to discuss your requirements, explore the best technical approach, and build a solution that is reliable, manufacturable, and optimized for production for your valuable investment.
