My product design career began in 2008. Prior to that, I worked for a company primarily serving South Korea's three major telecom operators, SKT, KT, and LG U+, as well as Brazil's Intelbras. At that company, I was responsible for reviewing client products and optimizing designs to better suit mass production and reduce manufacturing costs. I also provided product development services to other OEM clients, taking full responsibility for early-stage product quality inspection specifications, mold review, new process development, component manufacturing, technical requirements, and cost optimization. Some of the client projects I led have reached production volumes of millions of units (these projects have been in production for many years). I have applied for one invention patent, several utility model patents, and design patents. Additionally, I worked in mechanical design at a medical company whose main product was extracorporeal shock wave lithotripsy (ESWL) (primarily used to treat urinary tract stones). My product design experience covers communication network equipment, smart home devices, 3C digital products, and medical devices. With over 15 years of product design experience, I am confident I can meet your needs. I would be extremely grateful if you would choose me.
