I am an hardware and embedded systems engineer with over 5 years of experience in PCB design, firmware development, and technical consulting for low-power electronic products. I specialize in battery-powered devices, wearables, and IoT systems, with a strong focus on power optimization, hardware reliability, and design for manufacturability. I have worked on projects for global clients across the US, Europe, and Asia, supporting the full product lifecycle from system architecture and component selection to schematic/PCB design, prototyping, debugging, and production readiness. My goal is to deliver clear, efficient, and production-ready engineering solutions. What I Offer: 1. Hardware Design PCB design and hardware development for reliable, manufacturable products Experience with multi-layer boards and common interfaces (USB, Ethernet, memory, wireless modules) MCU and SoM-based designs (STM32, ESP32, Nordic, Raspberry Pi CM, Jetson, Rockchip, NXP) Power, analog, and basic motor control circuits DFM/DFA awareness to support manufacturing and compliance Tools: Altium, KiCad, EasyEDA; basic 3D/CAD support for enclosure alignment 2. Firmware & Embedded Development Embedded C/C++ development with supporting scripts/tools (Python) Wireless and IoT systems: BLE, Wi-Fi, Cellular, LoRa, MQTT, cloud integration Driver development and common protocols (I2C, SPI, UART, RS485, CAN) Embedded UI support using lightweight frameworks when needed 3. Product & Project Experience Startup and small-team environments with a strong product focus Experience coordinating hardware, firmware, and prototyping workflows Practical problem-solving, debugging, and iterative improvement during development 4. Why Work With Me Clear, product-oriented engineering approach Balanced focus on performance, cost, and manufacturability Reliable delivery and transparent technical communication If you’re looking for an engineer who can support your product from concept to working hardware, I’d be happy to connect.
