I can support your project at every stage, including calculation and simulation, proof-of-concept (POC), schematic and PCB design, firmware development, and preparation for mass production. I focus on practical, working solutions that meet real-world constraints such as reliability, power consumption, and manufacturability. My core expertise includes: IoT Development I design ultra-low-power IoT devices with consumption down to the microamp (µA) level. I have experience building systems based on wireless technologies such as Wi-Fi, BLE, and LoRa, optimized for battery-powered and long-lifetime applications. Schematic / PCB Design and Review I provide professional schematic and PCB design, as well as design review services. I consider signal integrity, EMI, thermal behavior, and production feasibility to ensure robust and manufacturable designs. Motor Drive and Power Electronics I have experience in AC motor control and power electronics applications, including the use of IPM, PIM, IGBT, and power MOSFETs, with attention to efficiency, thermal design, and system stability. High-Reliability Industrial and Automotive Electronics I develop industrial control nodes and automotive-related electronic components based on advanced platforms such as Texas Instruments, Renesas, and NXP. I understand the requirements of high-reliability systems and long-term operation in demanding environments. Additional Value: For IoT and industrial device development, if your project requires a PC-side application or a mobile app, I can also support development up to the minimum viable product (MVP) stage for functional validation. I work with a strong engineering mindset, clear communication, and a focus on delivering reliable, production-ready solutions. 收起 -

I help people turn ideas into real working products, from early concept to prototype and manufacturing-ready files. My work covers both the electronics side and the mechanical side, so I can help when a product needs a PCB, enclosure, structure, wiring, assembly design, or full product development. I like working on practical designs that are easy to build, easy to test, and ready for real use. On the electronics side, I can help with: * PCB design and layout * Schematic design * Circuit review and troubleshooting * Power supply circuits * Sensor and control circuits * Microcontroller-based systems * Wiring diagrams * BOM preparation * Gerber files and manufacturing files On the mechanical side, I can help with: * 3D CAD design * Product enclosure design * Mechanical parts and assemblies * Sheet metal or plastic part design * Prototype design * Design for manufacturing * 2D technical drawings * Assembly drawings * Mechanical improvements for existing products I can also help review an existing design and find problems before manufacturing. Many small issues in PCB layout, enclosure clearance, mounting holes, wiring, heat, or assembly can become expensive later. I try to catch those problems early and keep the design simple and reliable. My usual goal is not just to make something look good on screen. I focus on whether the product can actually be made, assembled, tested, and used properly. I care about clear communication, clean files, and practical engineering decisions. I can support you with: * New product development * Prototype improvement * PCB and enclosure matching * CAD model changes * Manufacturing file preparation * Product redesign * Technical drawings * Engineering consultation I’m comfortable working with clients who have only a rough idea, a sketch, an old design, or a product that needs fixing. You can explain the problem in simple words, and I’ll help turn it into a clear engineering plan. Before starting, I usually like to understand: * What the product should do * How it will be used * Size or space limits * Power requirements * Manufacturing method * Any current problem in the design This helps me give better suggestions and avoid unnecessary work. If you need someone who can think about both electronics and mechanical design together, I’d be happy to help. 收起 -
