I have been working as a developer and a trainer of object-oriented software development for almost ten years in Japan.. Now, I am a freelance consulting engineer of object-oriented or software agent technology I am also well informed about UML and agile development process. I have been working on mainly object-oriented developing projects with Smalltalk or Java. And then, I was granted 2004, 2005 IPA Exprolatory Software Project managed by Dr. Alan Kay. In that grant, I developed two software agent systems for children.
