• AI-Powered Job Matching:
o Integrate a Machine Learning/NLP model (TensorFlow/Scikit-learn) for automated matching between job seekers and vacancies.
o Implement a self-learning system that improves over time based on previous placements.
• Document & Email Management:
o Implement a document management system that supports auto-generated Word/PDF documents.
o Set up an internal email integration for direct communication within the CRM.
• Scheduling & Notifications:
o Develop an advanced scheduling module that includes automated workflows, reminders, and notifications.
o Enable real-time updates for upcoming deadlines and system alerts.

• Machine Learning: TensorFlow, Scikit-learn, or similar
• Security & Compliance: OAuth, GDPR implementation
