Hello, Everyone! I am an embedded systems engineer, PCB designer, and firmware developer with over 10 years of professional experience. I provide complete, end-to-end solutions for a wide range of electronic device designs, supporting clients from initial concept and schematic design to PCB layout, prototyping, assembly, and full system testing. I have strong expertise in high-speed PCB design, including PCIe and DDR4 routing, as well as precise impedance matching for reliable performance at high frequencies. I also specialize in RF and antenna design for modern IoT devices, ensuring optimal signal integrity and system efficiency. In addition, I have deep experience in ultra-low power design, achieving microamp and sub-microamp current consumption for battery-operated and wearable systems. I specialize in firmware development for LTE-GPS-LoRa-BLE-based embedded systems (nRF52 series), including low-power optimization and high-precision sensor acquisition. My focus is on delivering robust, production-ready solutions with high reliability and performance. 🔥 Main Skills 👉Embedded Systems 👉Schematic Circuit Design(Low Power consumption Design) 👉Firmware Development(All Microcontrollers-STM32, TMS320, ESP32, FPGA, nRF52, Raspberry PI) 👉PCB Design(High speed signal routing, PCIe, DDR4, 18 multi-Layers Design, RF antenna Design,) using Altium Designer, KiCad, EasyEDA, Fusion 360(No problem in DFM-JLCPCB) 👉IoT with nRF52(BLE), LoRa(for example, SX1262), LTE(SIM card interface), GPS and other variety of sensors 🛠️Tools & Technologies: 👉 nRF5 SDK / nRF Connect SDK 👉SEGGER Embedded Studio + J-Link debugging 👉 C/C++ (bare-metal & RTOS) 👉 BLE GATT, LTE AT commanders, custom wireless protocols 👉SPI / I2C / UART / ADC integration 👉Low-noise measurement systems (nA level) 👉STM32CubeIDE, Cube MX, Keil, CCS, Arduino, ... 👉MQTT, Free RTOS, Zephyr RTOS 🚀 I can support your project from concept to production.
