    Thank you for visiting my profile. My name is Andy Mei. I am an experienced electronics design engineer with more than 10 years of practical knowledge. I can design electronic devices from initial idea to final product. Including schematic design, PCB design, microcontroller firmware coding, and prototype making. Especially for the PCB design, I can implement 3D visualization of the components while designing the PCB, so you can see the 3D effect of the PCBA before the PCB is physically produced, and you can verify if the mechanical space is suitable in advance. This can save a lot of overall product design time. I have PCB design experience with 2-layer, 4-layer, and 6-layer boards and can meet your different PCB design needs. I have rich experience in the development of traffic signal controllers. As an engineer with over 15 years of experience, I have accumulated extensive expertise in electronics product design, manufacturing, and supply chain management (SCM). Related products include consumer electronics, household appliances, and industrial automation. I can use SOLIDWORKS to draw 3D mechanical drawings and design mechanical parts for customers. I have an office in Shenzhen which is the industrial hub of South china.and very close to Dongguan too. I can represent your company to do sourcing, material sampling, and production validation. My Skills: Schematic Design PCB Design (Altium Designer) Gerber Generation BOM making & material Sourcing Supply Chain Management Firmware development Software design Mechanical design (solidworks) Sourcing in China Production Monitor Quality Control
