Thanks to Pierre, I now have a great Chrome extension: smooth, functional, with a top design. The extension precisely meets my expectations and can interact with my ATS!
Pierre perfectly understood my needs and was very responsive whenever I needed him to make improvements to the extension.
Furthermore, he was very methodical, systematically noting my feedback and providing regular updates. He also proactively suggested improvements that were implemented.
