Who can build a client portal for my agency?
Marwan Ayman builds secure client portals where customers log in to see project status, tasks, files, invoices and messages while your team manages everything from an admin dashboard. This portfolio runs its own portal built with Next.js, Prisma and role-based access control, so the demo you are shown is production software rather than a mockup.

The short version
- Typical timeline
- 4–10 weeks
- Typical range
- $5,000 – $20,000
- Live reference
- The portal running on this site
- Access model
- Query-level scoping, not interface filtering
In more detail
Most agencies do not need the portal to replace their project tool. They need it to stop the same four questions arriving by email: where is my project, what do you need from me, where is that file, and what have I been invoiced. A portal that answers exactly those four questions can ship in weeks rather than months.
Access control is the part that has to be right on day one. Every query is scoped to the signed-in client, not filtered in the interface, so a client cannot reach another client's data by changing an identifier in the URL.
Integrations that carry their weight: Stripe or PayPal for invoice status, file storage for deliverables, and email or WhatsApp notifications so people learn about updates without logging in to discover them.
