RestAPI development - Bachelor Degree Project

The main objective of this project is to create a platform to facilitate communication and transfer between those who can supply a used car part (individuals, car parks, car parts stores) and those who need such a part (people physical, car services) by placing SELL(ro. VAND) type ads (selling part X) as well as placing LOOK (ro. CAUT) type ads (looking for an audi a4 throttle, model x, year y + pictures) similar to groups on different platforms socialization. An adjacent object is the creation of a FORUM type section with the possibility of discussion regarding all the services available in and adjacent to the automotive field (eg mechanic, car service, car electrician, etc.…). In addition to the current OLX and AUTOVIT ad placement platforms where the placement is made in VAND form and those who have a need are forced to look for those who provide that good or service, we come with the FORUM side, where can develop different discussions on different topics and also help the placement of the site in Google indexing as well as the concept of CAUT where a user has the possibility to place a CAUT ad a piece x, and those who own that piece (individuals, service- shops, car parts stores, dismantling parks), have the possibility to view a list of CAUT type ads, and can contact them by phone and offer them, if they manage, the part of interest. The main goal is to create a virtual car parts fleet. We aim to be a hub for those who have a car part for sale (used). So, i want a web app, android app and ios app that use the same API.
