Looking for a frontend developer for Ziba.travel

Good afternoon. Were a young start-up in the Travel Theme (ziba.travel). We are looking for an employee who owns a part-time job on a remote basis.
We are now on the finalization of the MVP version to launch. There is a need to finish a couple of things associated with adapting to the mobile version and correcting the addition of new functionality. We offer payment in stages for the completed task or hourly. Conditions are negotiated individually.
Open to interaction and cooperation.
