Idee

Meie idee oli luua veebirakendus BurgerAce, mis võimaldaks klientidel ette tellida burgereid. Mõte on selles, et meie klientidel on võimalik burgereid ette tellida. Seetõttu kiire elutempoga kliendil pole vaja oodata toidu valmistamist. Klientidel on võimalik koostada etteantud komponentidest omale meelepärane või valida eelnevalt valmis tehtud burger. Meie teenus vahendab kiirtoidukohate ja nende klientide vahelist suhtlust. Burgeri ostmine pole varem nii kiire ja mugav olnud! :)
