about

I am interested in development and optimization of scientific, high-performance and/or mission-critical software to solve complex problems, in a C/C++ and Linux environment.

My background is applied maths extended to software engineering. During my PhD (2012, ENS Cachan), I designed and managed IPOL, an online research journal, code repository and web image processing service to improve the quality of software in the research community and increase the impact and partnerships of our research group. Then I worked with researchers to improve the quality and performance of their codes.

Since 2009 I have been living in Japan.

My resume is rarely updated. Ask me if you want to know more.

development

• git repositories, with some codes for the IPOL architecture, some IPOL articles, some support code fragments. Some of these repositories are mirrored on Github.
