Software Engineer - France

LinkedIn

I am an enthusiastic software engineer living in France.

I have been working as a software engineer in France and the United States for more than 10 years, in many different sectors such as insurance, hotel, mobile phone and wedding industries.

My main skill is back end development with JavaEE. I also have a good front-end experience with JavaScript frameworks, HTML5/CSS and advanced knowledge in server administration, especially Unix-based ones.

I am curious and try to stay up-to-date by attending tech meetups or conferences when I get the chance. And I use some personal side-projects to experiment new things.

Beyond development, I believe in agile methodologies, especially in Scrum since I have used it with success throughout my career and became a certified Scrum Master.
In addition to that, I like the software craftsmanship approach.

I am looking for an opportunity to work for a company I believe in, with challenging engineering problems, where creativity and user experience matters.
