I have a nearly completed web application, developed in Python, Next.js, and PostgreSQL, which is approximately 90% done. The project is complex, with many features already implemented, but requires finalization to make it production-ready. Specifically, the tasks involve bug fixing and debugging, adding any missing features, and optimizing performance and scalability. Attention needs to be directed towards database/backend updates, refining the frontend design and user experience, and ensuring all necessary project tests are verified. Additionally, the code and files must be thoroughly reviewed, cleaned, and organized. The primary goal is to ensure the codebase is clean, maintainable, and prepared for long-term scalability while addressing any outstanding development areas. I'm looking for someone with expertise in these technologies and a keen eye for detail to help wrap up this project to production standards. the app is running but it needs to be finalize in all the aspects.
