I am interested in your request, I have extensive experience in developing CRM/ERP systems, both our own and with modifications from Open Source platforms. We have a sufficiently diverse stack, so we can develop on React, or after analyzing your requirements and wishes, we will suggest other technologies (if a better alternative is possible).
In our portfolio, we have our custom CRM system, the first version on Vue.js, the second on Angular. Do you already have a technical specification? Let's communicate in more detail so that I can more accurately orient you on timelines and costs.

I have already worked on similar B2B projects. Among the cases is a CRM system for a financial institution in the UK, where there was more complex logic, integrations with payment providers, and even artificial intelligence modules (including NLP data processing and analytics). With this client, we also did other SaaS projects, but everything is under NDA.
I also have experience with a Ukrainian IoT startup: we developed an admin panel and user dashboard for managing "smart" boilers and heaters, connecting mobile applications. We used the stack Vue.js + Laravel + MySQL, deployed the infrastructure on DigitalOcean. Despite the different framework, the essence was similar — large-scale frontend, integrations with third-party services, and complex logic.
To understand how exactly I can help you, please clarify:
1. What are the main features you plan for this CRM — are integrations with artificial intelligence or other external services expected?
2. How large is the frontend and what timelines are you considering?
… 3. What is your stack on the server side to agree on REST integration (DevOps approach, environment, etc.)?
I would be happy to discuss the details in private. Write to me — we will discuss how I can help!
