You can get a good idea of a Doer’s reliability and skill level by checking their profile on the HUDU app. You’ll be able to see the Doer’s rating and reviews left by previous Listers. This will give an overview of the Doer’s experience and customer satisfaction within the app. It’s important to note that it’s always a good idea to communicate with the Doer before awarding the project to get a sense of their qualifications and work style. This can help you make an informed decision and increase the chances of a successful project outcome.
