Message from the Managing Director
Sunny System Ltd. is an independent IT company that is established in Bangkok, Thailand in 2009. Since the establishment we have been providing IT solution services mainly to Japanese oriented companies in Thailand. Our main business is to provide one-stop IT solutions not only applications development and implementation such as production management, inventory management, sales management, and human resources management systems, but also selling, installing, and maintaining of IT equipment such as servers and network.
Whether you don't know where to gegin with or you don't know to whom to ask some advice, you can contact to us. We will suggest the best solution from our experience that we have accumulated over 18 years and our partner network.
Nowadays, the lack of skilled IT personnel has been an issue in Japan. To make up for the shortage of human resources, we had started offshore development from Japan. In order to make a better proposal, we would be happy to hearing from you, and then we can start working together.
With all of the employees united, we will do our best to satisfy you. And we are looking forward to working with you in the future.
Managing Director Hiroshi OHINATA
Tell us where IT gets in the way. We will take it from there.
Consulting, implementation and after-support — from one team that has been doing it since 2009.
