For initial research to the final prototype I can do it all for you. I will focus fully on user-centered design focusing on usability. After conducting several usability testing and interacting when I feel the app is ready to onboard then I will finalize it.

First I will do initial product research(if not done yet). Then I will start solving the user problem with sketching and trying proposing several solution for that. After confirming the sketching I will go with the low fidelity design. With the low fidelity design after conducting usability testing and iterating over again and again finally I will do the prototyping and developers handoff.
