Mile Kft. is the largest electricity trading company in the country. We were tasked with replacing the old outdated corporate website, which conveys the company's visions and philosophy, so we designed a completely new web design starting from scratch. In the field of development, it was a unique solution to write a search engine for the complex system of the company's sectors, product families and represented suppliers, which gives highly relevant results for the most common keywords about products or the contact information of the responsible colleagues. We designed a responsive newsletter image for the website and customized a newsletter system so that the company could carry out targeted newsletter marketing.
