- use existing variable as most as possible (portal, result) ;
- avoid call `getTitle` on the same object in a loop (project.getTitle()) ;
- avoid compare projects by title as many projects may have the same ;
- avoid using `set` as service id cannot be present twice (set(service_pairs)) ;
- optimise catalog request to get project (limit) ;
- optimise catalog request to get sale supply (destination_project_uid) ;
- rename plurals in variable (service_pairs) ;
- rename abbreviations in variable (*_obj) ;
- remove trailing spaces.
