ZentroStack – Multi-Tenant SaaS CRM, Built with AI

Portfolio project
Rajeeb Mookhopadhyay
The goal: Build a CRM that small businesses can actually afford and use, without the complexity of the big platforms.
What I built: • A multi-tenant SaaS platform: each business gets its own secure workspace • Lead and contact management with a visual sales pipeline • Automations for follow-ups and lead routing • User accounts, roles and a clean dashboard
How: I designed the product and architecture myself and used AI-assisted development to build it. I have a programming background, so I review and debug the code. That let me go from idea to a working SaaS product in a fraction of the usual time and cost.
Why it matters for clients: If I can build and run my own SaaS product, I can build yours: an MVP, an internal tool, or a custom CRM.
