How I design platform architecture

Platform architecture begins neither with page design nor with the choice of technology. First, I define who will use the system, which tasks they must perform, and which information each person is permitted to see.

A single platform can have different roles: client, manager, partner, employee, and administrator. A separate workflow is created for each role. The client submits an enquiry and tracks its status, the manager processes requests, the partner adds their own clients, and the administrator controls the entire system and its access permissions.

Once the roles have been defined, I design the sections and personal portals. I then describe the flow of data: how an enquiry is created, who receives it, which statuses it passes through, when a document is generated, how payment is recorded, and at which point a notification is sent. These connections are what transform a collection of separate pages into a functioning digital product.

The database, files, integrations, analytics, activity log, and security are planned separately. It is also important to divide features in advance between the initial launch and later development stages. This makes it possible to release the core version faster without creating technical restrictions for future scaling.

Good architecture is invisible to an ordinary user, yet it determines performance, security, ease of development, and the cost of future changes. The more precisely the system is designed before development begins, the fewer expensive revisions will be required after launch.
