Alexis Bernard

We run RorVsWild to help teams to monitor performances and errors of their Ruby on Rails applications. I am available for consulting to optimize and resolve bottlenecks of Rails applications.

I previously worked for the following companies: Official.fm, Versapay and Pierlis.

I enjoy riding my motorcyle in the summer and skiing on fresh powder during the winter. I have a blog in french about my motorcycle races.

You can find me on Twitter, Bluesky, GitHub and LinkedIn, or reach me via my contact form.

I blog sometimes
