Hello!

I've worked on many backend development projects for content and product management systems using Node.js, including building APIs for integration with various e-commerce platforms. I have experience developing solutions that allow you to efficiently manage large product catalogs and seamlessly synchronize with the front end.

I can develop a scalable Node.js backend for your product management system using Express.js and MongoDB/PostgreSQL. The architecture will be built using a microservice approach, which will provide flexibility and the ability to extend functionality further. I can also implement a strong authentication and authorization system, provide fast APIs, and optimize database queries to efficiently manage large volumes of products.

How much data do you plan to process in the system and what specific integrations with other platforms do you need? Also, what is your time horizon for the development of this project?

Hello, sir
I have read your description.
I have a few questions regarding the project description.
1. Which database and hosting environment do you prefer?
2. Do they want SQL (PostgreSQL, MySQL) or NoSQL (MongoDB)? Where will the backend be hosted (AWS, Azure, locally)?
3. How will the system integrate with their website or online store?
4. Do they need APIs, webhooks, or direct database connections?
I would appreciate it if you could inform me about these questions.
I hope to work with you.
… Best regards
Stanislav
