About Us
Built by people who've done the work
K&J was founded in 2019 by Kenny Neo and Liang Jie — two engineers who, between them, have spent over 36 years experience in the field. They didn’t start the company to scale fast. They started it because they knew how good this work could be when it’s done without cutting corners.
That conviction shapes everything: who we hire, how we plan, and what we’re willing to put our name on.
精益求精 — a relentless pursuit of better — isn’t a marketing phrase for us. It’s how we were trained, and how we run the business.
