Experienced React.js and Django Developer for Depot Platform Feature Modifications

I'm looking for an experienced developer to support the modification and improvement of our existing Depot platform.
The platform has recently been restructured using a more scalable and maintainable architecture based on Next.js 14, Prisma, PostgreSQL, TailwindCSS, and shadcn/ui, as this stack provides a more rational and efficient foundation for long-term development.

The project is divided into two separate platforms:
- A user-facing platform for end users
- A dedicated admin panel for administrators and operational management

The primary goal of this project is to implement specific feature modifications and improvements to enhance overall functionality, usability, and security while leveraging the existing codebase.

Key problems to be addressed in this project include:
- YouTube integration, including embedded content management
- PDF upload functionality for weekly notifications and announcements
- Excel file upload and embedded viewing for managing and displaying weekly schedules
- Security improvements, including proper authentication, authorization, and secure file handling

The ideal candidate will have extensive experience with Next.js / React development, a strong understanding of Prisma and PostgreSQL, and experience building and maintaining admin panel architectures alongside user-facing platforms. The developer should be comfortable working within an existing codebase and delivering clean, maintainable, and high-quality solutions.

Clear communication, attention to detail, and the ability to work efficiently are essential for this project.
Furthermore, the goal is to utilize all available AI tools to complete the required work within approximately 4 days. Developers who are adept at using AI tools to generate code, accelerate development, and optimize workflows are strongly preferred.
