Full Stack Senior Developer For Debugging, Analyse, Improvements

I need a skilled developer to fix some bugs in my app and integrate a new database. The bugs need to be identified and resolved to ensure a seamless user experience. The project is a fully functional travel platform that is currently running in a production environment. The developer will need to work closely with the client to define the scope of work. This involves conducting a thorough analysis of the client's needs to determine necessary functionalities and repairs that need to be implemented. The developer should be proactive in identifying potential improvements and offer solutions that align with the client's goals. Effective communication and collaboration will be essential to ensure the project meets expectations and is delivered on time.

•⁠ ⁠The web app is developed fully in React, Node.js, MongoDB with AWS on Server Side, so deep knowledge and experience in full-stack development are essential.
•⁠ ⁠The new database to be integrated is a PostgreSQL database. Therefore, strong PostgreSQL skills are also required.
•⁠ ⁠Since the nature of the bugs has not been specified, a keen eye for detail and strong problem-solving skills will be crucial.
•⁠ ⁠Additionally, there will be a need for new API integration's.

Intellectual Property Rights: The rights to intellectual property, source code, and design are and will remain exclusively with the client.
Confidentiality: Ensured through a signed NDA

Please provide examples of your previous work with Node.js, React, and PostgreSQL in your proposal.
