Multi-Tenant CRM Backend Development & WhatsApp Bot Integration
I really enjoyed working with Syed on this project. He played a key role in developing and improving the backend, supporting the AI logic, and helping structure the system to move toward a scalable SaaS solution. He was always responsive, proactive, and open to feedback, which made collaboration smooth and efficient.
Syed showed strong technical ownership and commitment, even when we faced external dependencies and blockers. I would gladly work with him again and recommend him for complex AI and backend projects.
