I am looking for a company to optimize a large website (store), based on proprietary solutions (technologies: PHP, JS, SQL, SASS, AJAX, the main frameworks are: Symfony, Doctrine, Sonata Admin, jQuery). Possible permanent cooperation in further development of the software. The key of the current order, is the independent identification of problems (affecting the slow operation of the site) and therefore the audit along with proposing solutions and implementing them. We would like to cooperate with a company with time available for this project. Please include an hourly rate in your proposed quote.
