How to find excellent mobile app developer?
The last part of your hiring process is gauging the prior work of developers. Check the profile of your prospective developer, which can showcase their skills. If they have developed apps and are found in the app store, take your time to download followed by playing the same. Check how these apps are rated, have a look at their reviews, play it to find bugs (if any), check how long the apps take to open, etc. Before you review the apps, you need to ask the developer/company to describe these projects and their feedback on the outcome.
These are some vital tips, which can help you in finding the best mobile app developer. Above all, you need to consider human elements as well, so follow your gut feeling (your instincts) as well while hiring a reliable mobile developer.
