I wanted to see and experience the world, so I decided to go to Japan.

I studied Japanese for a year and joined Porters Corporation.

My three years at Porters Corporation were the most valuable experience of my life. It was my first job, but I met many good people and, we became friends.

The company was full of professionals who take ownership of their products and truly enjoy their work. From them, I learned two of the most important qualities for my career: responsibility and passion.

I spent my three years at Porters Corporation not just as an employee, but as a friend to everyone.
