programmer unity

I search a programmer for Unity . I want to finished a game that I created in home by Covid-19. I need that the object when it's drop in the box correct, don't move other time.

This is the code:

     public void DragObjeto5()
 {
     Objeto5.transform.position = Input.mousePosition;
 }
 //public void OnEndDragObjeto1(PointerEventData eventData)
 //{
 //    Objeto1 = null;

     //        if (transform.parent == Objeto1 || transform.parent == transform.root)
     //
 //    {
 //transform.position = startParent.transform.position;
 //    transform.SetParent(startParent);
 //    }
 //    GetComponent<CanvasGroup>().blocksRaycasts = true;
 //}
 public void DropObjeto1()
 {
     float Distance =  Vector3.Distance(Objeto1.transform.position, Objeto1_Lugar.transform.position);
     
     if (Distance < 50 && Objeto1Correct == false)
     {
         Objeto1.transform.localScale = Objeto1_Lugar.transform.localScale;
         Objeto1.transform.position = Objeto1_Lugar.transform.position;
         Objeto1Correct = true;
         Objeto1_Lugar.name = Objeto1.name;
         source.clip = buttonDrop;
         source.Play();

     }
     else
     {
         Objeto1.transform.position = Objeto1Ini;
         source.clip = reload;
         source.Play();
     }
 }
