Hello, Vladimir.

I am ready to join the project. I have experience with MERN (MongoDB, Express, React, Node.js) and NestJS — I have worked both on writing backend from scratch and on modifying someone else's code.

Please clarify: – What is your backend currently built on: NestJS or Node/Express?
What exactly needs to be implemented or improved in the CRM: authorization, booking, notifications, reports?
Is there documentation or a technical specification to assess the scope of work?

I am ready to discuss details and get started.

Good day!
I have experience creating a CRM system from scratch for booking bus tickets on the NestJS + PostgreSQL stack, with support for authorization, order management, seats, routes, and users.
I have a good understanding of the MERN stack architecture, have worked with MongoDB, Express, React, Node.js, and also actively use NestJS in production projects.
I am ready for both refining an existing system and developing from scratch. I can quickly immerse myself in the project, propose optimal solutions, and ensure high-quality implementation.

I would be happy to discuss the details!
