I'm a solo, non-techncial founder and need someone to help me build and launch a mobile app. I had a previous team build a semi-functional prototype in TestFlight and have identified a number of areas in which certain features aren't working as envisioned. The project involves leveraging the work done to-date on the existing app to ensure it is user-friendly and aligns with the project vision. The ideal candidate should have experience in mobile app development and be able to work iteratively to improve the app's functionality and design. As we move forward, I can provide GitHub access to the underlying code the team has delivered to-date as well as inviting you to as a test user in TestFlight and sharing the notes I've compiled on desired improvements / changes. I'm open to a fee arrangement or, with the right person/group, a longer-term / creative partnership.
