I'm are looking for a developer to review, fix, and complete an existing project that currently has several technical and functional gaps. On the technical side, the project requires corrections to backend configuration and security. This includes resolving incorrect CORS package usage, completing the authentication flow, and fixing general configuration issues that are causing instability. From a functionality perspective, several core features are incomplete. Asset management calculations need to be finalized, portfolio performance tracking requires proper implementation, and the overall logic should be reviewed to ensure accurate results. In addition, the UI/UX is outdated and must be modernized. The interface should be clean, professional, responsive, and suitable for a live demonstration. This is an academic project with a strict deadline of January 15. The final deliverable must be stable, fully functional, demo-ready, and visually polished for presentation purposes. Developers with experience in debugging existing codebases, authentication systems, data calculations, and modern UI design are preferred.
