Comprehensive Client Portfolio Management System

I am searching for an expert developer to construct an advanced client portfolio management system that will simplify the collection process. Fundamental features include:

- Cobranza: Implementing a cobranza system should be a primary focus. This will allow us to manage our clients effectively.
- Automatic Reminders: The system should automatically generate reminders helping us establish a consistent schedule.
- Payment Tracking: Keeping a record of completed and pending payments should be effortless with this system.
- Reporting: Regularly generated reports provide an overview of the collections process status.
- Multichannel Alerts: The system should be capable of sending reminders and alerts via WhatsApp, SMS, Email, and even via call center.

The ideal candidate for this project should have substantial experience in developing business management systems, especially those dealing with client portfolio management and collections. Proficiency in designing cross-platform alert systems will be a major plus. This project requires you to understand our workflow thoroughly and tailor the system to streamline it. We are looking forward to professional and creative problem-solving strategies.
