When starting a new technology- focused business, some of the things you need most from your mobile app developer are timely communication, sufficient skills, and the ability to interpret non-developer language. Solomon excels in all three areas. He made me comfortable along the development process of my app by staying in constant communication with me and replying in a timely manner. Solomon let me know of any issues as they came up, which allowed me to stay on top of my business planning. I would not have been able to successfully launch my company without Solomon's abilities. I highly recommend him to work in any capacity!" - Upwork Client "Solomon is a great guy to work with. Goes above and beyond and even out of his own way to find better solutions and implements it. It is a pleasure to work with him again and going forward he will be our go to person for all iOS projects." - Upwork Client Message me now if your looking for an expert mobile app developer to get started on your project!
