We need some fixes and changes to current Prestashop installation. There are multiple technical tasks as well as some UI fixes and/or layout changes. You should be expert with PrestaShop as some of the tasks may require changes to PrestaShop core files and/or getting latest changes from official repository. Also PrestaShop upgrade to latest version is needed at some point. If job quality is affordable we would like to have continuous contract with you. We're looking for a person that could be able to do both UI fixes and technical changes.
