app develper

I am looking for a PT full-stack developer to manage an existing proprietary app that's being released for iOS and Android platforms this month. The candidate should be equipped to address any bugs or issues that arise during its deployment, implement fixes, updates etc to existing features, work with our designer to update the app design, and implement new features as we get feedback and iterate. This is currently a part-time salaried position (20 hours per week) with potential for full-time employment if the need arises. Must be proficient in react native and node.js.
