About me

Hi there ! My name is Pascal Baillehache, I'm a French computer science engineer, 47 years old, living in Japan since 2005. This page is a short introduction of some of my personal and professional accomplishments (from newest to oldest). A PDF version is available here (日本語の履歴書はここにあります).

I'm open to new opportunities !
So many social and environmental problems need to be solved urgently, I do not wish any more my labour to profit the personal and short-term benefit of a few greedy ones. If your project is concretely related to solving these problems (global warming, environmental degradation, inequality and discrimination, corruption and criminality, etc...) and my skills may serve you, I would really enjoy having a chat with you. You can send me an email, or contact me on LinkedIn.
