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.

I am a computer aided design engineer, that helps people create consumer products. Whether electronic or mechanical, I can take you through the product development process. I specialise in electronic enclosures and products that are mechanical in nature. I create 3D models that are parametric, easy to modify and make.

Having graduated from university with a product design qualification I established myself as a freelance designer helping companies and individuals develop their products and ideas into 3D and creating parts ready for manufacture or prototype. Two years ago I co-foundered a technical design agency offering creative and technical support. We've worked with some big names such as Samsung, Lotus, Dyson, Courvoisier, Pelican, and Softbox to help develop point of sale stands, and product ranges. We use the latest CAD software to develop our models mainly utilising SolidWorks to create technical models, drawings and renders.
